BCMI collections not accepting multiple records

[jakemorr]

Describe the Bug
when attaching multiple new records to an existing BCMI collection, a range of undesired behaviours can occure including (collection not being updated, collection would be completely emptied and all records would be removed, most common: it would remove all existing records and only add the new records)

Expected Behaviour
it should create an update and add the records to the collection alongside the existing records

Actual Behaviour
described above, doesn't delete underlying records but does leave them in a broken state where the records believe they are still apart of a collection, but the collection is empty and the records cannot be added back using the UI, needed Dev to go into DB to fix.

Implications
users give up on updating BCMI Collection, causes user to abandon application, very poor user exp.

** Steps To Reproduce**
Steps to reproduce the behaviour:

1. Go to NRPTI, All Mines Section,
2. Click on a mine
3. go to an existing section under a mine.
4. click on create or add a new record to an existing collection
5. add multiple records and click update
6. See error

Additional Context

• Could be programmed in a way where it deletes everything in the collection and then rewrites it every time
• there is no UI to inform the user that an error occured
• this isn't an uncommon upload path for getting records into NRPTI
• this error is only with BCMI
• most collections only get created with one record and its not a problem, only when its multiple records does the issue begin happening.
