Hi Danssmith1,
I 'm glad to help you. I have made a test using same version of Excel on MAC and the function of formula works regularly.
For the issue you have, Please try following steps firstly:
1. Select the cell.
2. Format the cell as "General". (Right-click the cell, select Format Cells, and choose "General.")
3. Delete the "=" at the beginning of your formula, and hit Enter.
4. Insert the "=" back in the formula at the beginning.
If the cell still display formula, please provide us the sample problematic workbook so we can do more investigation by our side.
You can press CTRL + ` (grave accent) to see all the formula in the cell. Does the V4 show formula regularly?
Waiting for your feedback. Thx!
Regards,
Eric
