Hi there @Jonathan!

This seems similar to a bug that's been reported where deleted columns are sometimes still referenced under the hood somewhere. I've added this thread to our internal report.

What I can suggest is deleting the table and starting a new one to avoid that reference being made. You can use that delete button in your last screenshot.

Thanks.. will creating the new table

Hi, any new tip to correct this bug?
Recreating a table can be really long..
