datamanager_init('User') save() "Duplicate entry" error in "usertextfield" table

[inmateaid]

This error occurred upon first use. The only existing record was the main admin and one test user account. The thing is, the record is added in lieu of the error so it seems like it's calling twice unless the call was actually successful and the error was after-the-fact.

I can truncate the tables to reset them if needed, but the initial user insert is where the userid comes from and is what's used as the primary key in the subsequent tables. So I don't see how that could be corrupted
