Out of curiosity, have you double-checked that your permissions are chillin’?
It’s worth double-checking your permissions in the base, the table(s), and for individual fields.
I’ve also found that strange behaviors can be caused by releases made by Airtable or from just simple bug fixes.
In those scenarios, I’ve always resolved them by logging out, clearing my cache, and logging back in.
If you cannot resolve the behavior, I recommend pinging Airtable support.
