Holdings source gets updated to MARC during importing from bib using nested profiles (affects Kiwi and Lotus)

Overview:

When updating holdings record with source='Folio' from MARC bib file we expect folio record to be updated but source of that record should remain 'Folio' because MARC bib (not MARC holdings) file was used.

This works fine with single match/action profile but behavior becomes wrong when holdings update is a part of nested profiles.

Affecting Kiwi and Lotus

Steps to Reproduce:

1. Create nested job profile like this:

2. Import valid MARC bib to trigger matched branch using created profile

Expected Results:

• SRS MARC created, Instance updated, Holdings updated
• Instance 'source' changed to 'MARC', Holdings 'source' remains 'Folio'

Actual Results:

• SRS MARC created, Instance updated, Holdings updated
• Instance 'source' changed to 'MARC', Holdings 'source' changed to 'MARC'

Additional Information:
Such profile performs well and Holdings source remains 'Folio':

This problem is reproducible on a snapshot environment, other environments were not tested.
