Each morning when I open my spreadsheets, I find that the graphs have been compressed and distorted by the insertion of “sub-title” into them. I spend several minutes deleting these and saving the change before I can get a proper view of my graphs. After inserting new data I close Calc and move on to other things. The next morning I find that “sub-title” has been re-inserted into all the graphs. How can I prevent this happening? This is now occurring every Monday morning instead of every day.
