ListView sorting changes columns to an old ListView

I’ve used SuiteCRM 7.11.15 for a bit as a user and had the default columns in most listview modules. I have since changed the default listview columns in the Studio for the modules that I wanted to change.
I have found that when I sort a column it will revert the listview to the original listview and I then have to manually add the columns back. Why do I have a ghost listview that appears when I sort columns?

Delete the filters, then create them again.

Unfortunately Listview filters conflate the two things: column settings + search filter.

Thank you. It was the filters. That worked.
