856$3 not mapping into holdings record (no numeric subfield mappings are working)

Overview: Cannot map data from a numeric subfield. (I tried using the $3 of an 856 field, but I think it's any numeric subfields). Regression - was previously fixed in MODDICORE-81

Current workaround: No great one, would have to edit the MARC file pre-import to change any numeric subfields to alphas

Steps to Reproduce:

1. Log into FOLIO-snapshot as diku_admin
2. Go to Settings/Data import
3. Create field mapping profile 1
   • Name: Create instance
   • Incoming record type: MARC Bib
   • FOLIO record type: Instance
   • Cataloged date: ###TODAY###
4. Create field mapping profile 2
   • Name: Create e-holdings with $3
   • Incoming record type: MARC Bib
   • FOLIO record type: Holdings
   • Permanent location: "Online (E)"
   • Digitization policy: 856$3
   • Electronic access:
     • Add these to existing
     • Relationship: "Resource"
     • URI: 856$u
     • Link text: 856$z
     • Materials specified: 856$3
5. Create field mapping profile 3 (only difference from profile 2 is that 856$3 is replaced with 856$a)
   • Name: Create e-holdings with $a
   • Incoming record type: MARC Bib
   • FOLIO record type: Holdings
   • Permanent location: "Online (E)"
   • Digitization policy: 856$a
   • Electronic access:
     • Add these to existing
     • Relationship: "Resource"
     • URI: 856$u
     • Link text: 856$z
     • Materials specified: 856$a
6. Create action profile 1
   • Name: Create instance
   • Action: Create
   • FOLIO record type: Instance
   • Link to Field mapping profile 1 (create instance)
7. Create action profile 2
   • Name: Create e-holdings with $3
   • Action: Create
   • FOLIO record type: Holdings
   • Link to Field mapping profile 2 (Create e-holdings with $3)
8. Create action profile 3
   • Name: Create e-holdings with $a
   • Action: Create
   • FOLIO record type: Holdings
   • Link to Field mapping profile 3 (Create e-holdings with $a)
9. Create job profile 1
   • Name: Create instance and e-holdings with $3
   • Accepted data type: MARC
   • No match
   • Action: Create instance
   • Action: Create e-holdings with $3
10. Create job profile 2
    • Name: Create instance and e-holdings with $a
    • Accepted data type: MARC
    • No match
    • Action: Create instance
    • Action: Create e-holdings with $a
11. Go to Data Import and upload the attached file: 856 with 3.mrc
12. Select the job Create instance and e-holdings with $3 and import the file
13. Go to Inventory and search for together alone
14. View the associated holdings, and check the Digitization policy and Electronic access/Materials specified fields to see if JSTOR-ADD-AGAIN populated into those fields
15. Go to Data Import and upload the attached file: 856 with a.mrc
16. Select the job Create instance and e-holdings with $a and import the file
17. Go to Inventory and search for together together
18. View the associated holdings, and check the Digitization policy and Electronic access/Materials specified fields to see if JSTOR-ADD-AGAIN populated into those fields

Expected Results:

• Data from 856 $3 should be populated into the Digitization policy and Electronic access/Materials specified fields when loading the 856 with 3.mrc file
• Data from 856 $a should be populated into the Digitization policy and Electronic access/Materials specified fields when loading the 856 with a.mrc file

Actual Results: The 856$a mapping works, but the 856$3 mapping does not. I think the problem may be with any numeric subfield in any field mapping profile. Needs checking with other subfield numbers in various free-text fields in instance, holdings, and field mapping profiles
