Please note this is a known issue with SplashID Safe record saving, with an easy fix.
Your record likely has a Note only. And/or it lacks a record name, and at least ONE field+field name for it.
The record name is next (right) to the record's icon. The field name #1 is below that, and below that is the actual field #1.
Please make sure to fill in at least these 3 fields/boxes, and then the record should save.
Also, make sure to not enter the fields wrong – field name #1 goes into the exact box for it, and not any other.
Likewise with field #1 – you cannot move it up or down, it goes just below its field name box.
And then your record should save fine, without showing the error.
Please see below for screenshots with correct & wrong ways to enter data.
