Why am I unable to delete columns in MS Lists?

Dr. Katrina Esau 0 Reputation points

I created a list within MS Lists. When attempting to delete or change column settings I receive an error. Deleting columns - it says it couldn't complete the delete to try again (see attachment). The column type box is greyed out and not allowed to be changed. Is there a way to change this to avoid column duplication?
