Table width bug

When restarting Scrivener, tables that previously looked fine now have all the right side columns super compressed and the left too wide. There seems to be no way to adjust column width.

I can post a screenshot if given permission.

What version of Scrivener for Windows are you using? I’m on 3.1.5 beta 2. I checked my tables and they have not changed. I have the same (unchanged) experience with version 3.1.4.
Were your tables created in Scrivener, or are they cut from other apps?
Some were created in Scrivener, some were copy pasted from excel, they all have the problem.

Did any from Excel include merged cells?
Scrivener for Windows can do horizontal merges and splits, but not vertical, like Excel and Word.

They did not include any merged cells.
