Formulas don't work after using To Actual function

Question

I had many cells with formulas pulling data from another spreadsheet. I ran the 'To Actual' function within Kutools which gets rid of the formula, while keeping the data in the cell.

Now however, I need to run some formulas in that same spreadsheet, but any formula I create, from very simple to complex, will not calculate.

Can you help me get my formulas calculating again.

Thank you
