How do I make mismatched formula warnings go away?

After changing the backend spreadsheet and regenerating the structure I am receiving a column formula mismatch warning for columns that were not changed. I looked endlessly for differences and the only difference in the columns the warnings were about was that the last row was a summation. The documentation says these are only warnings, not an error and if understand it correctly it happens the first time a structure changes. So, I have regenerated the columns several times, but the warnings will not go away. What am I doing wrong?

Can you post a screenshot of these warnings? Also perhaps the formulas in question?

Maybe try just a simple Save instead of regenerating?

Thanks, that worked. I had assumed that when regens also so a sync it was the same thing as a save. Goes to prove the old statement about assume = makes an … you know.
