Airtable columns missing in glide

What reasons are there for airtable columns now showing in glide.

Simplified example:

Airtable - Meetings
ID
Date
Attendees

Airtable - Actions
ID
Item
MeetingID

Airtable - Decisions
ID
Item
MeetingID

In att cases the MeetingID field isn’t showing in Glide, but is visile in Airtable. This i just a numeric fiel.
I have tried renaming. No help
I have tried changing to text. No help
I added a different new field as a test. This was visible
I have refreshed data sources

Thanks in advance.

Have you tried re-adding the base from scratch?

Not yet. I’m trying to figure out where to do that. I don’t see airable listed under data sources when I go to Settings>Data
