Receive error when attempting to check-in items on Lotus BugFest

Overview:
Steps to Reproduce:

1. Log into Lotus BugFest as the folio admin (folio/folio)
2. Check out an item to a test patron
3. Check item back in

Expected Results:
Item is checked in and appears on the top row of the Check in page

Actual Results:

(Note: Even though the message says the item was not checked in, it was.)

Additional Information:

• This happens on Lotus BugFest, but not Snapshot.
• This error did not occur during Lotus BugFest--something happened afterward.
• This doesn't happen if an item is checked in that has an Item Status of "Available" (e.g. it was used in-house).
• This error does not appear for every user, but does appear for the folio admin account, Holly Mistlebauer's admin account and Laura Daniels' admin account. Charlotte Whitt has reported that this works for her.
• We originally thought the issue was related to lost items being checked in, but it has proven to not be just lost items,
• Holly attempted to change the permissions for her account but received this error...
