I have a table, originally an .xls but saved as an .xlsx now that I switched to Excel 2016. All cells have been formatted as text.

When I open it, I get an error message about circular references and formulas--but as far as I can tell, I have no formulas, just words and numerical data.

Having to click past the message every time I use the file is a very minor nuisance, but is there some way to get rid of it?
