The older version of Excel has a hard stop at the number of formats a specific file can have. The file needs to be saved as the new XLSX format.

Open the Excel file from within Engagement
Select File > Save as XLSX to your desktop > Close the file
Drag the file back into the Engagement Binder and update the properties as needed
Remove the original file
Express sync to the KSM CFR when available
