Zoom Docs table column mysteriously disappearing

[mborges-mpf]

Hello.

If anyone can help me, i had a issue with a table in Zoom Docs. I created a table with some columns, but one of these were not seen by my job partner. At the next day, this column just had disappeared. If I try to create the same column again, the alert is displayed: "Enter a unique column name".

I did something wrong?
