Cloudkit Write Permission error for some records

I have a Mac OS X app which has around 15 tables.  These have worked fine for multiple years. I am in development mode for this container.  I recently added a new table, adding it automatically as I created records from the app.  I have created about 10 sample records in it, some from a different machine than my dev Mac.  For 2 of these records, in an attempt to save, I get this error:

<CKError 0x600000d7b5d0: "Permission Failure" (10/2007); server message = "WRITE operation not permitted";

From the dashboard on my dev Mac, I can retrieve the record, changed it, and save from there.
