Excel output for Tenant Assessments is needing file repair

Using 14 day trial to see what data is available. all Excel files from the various microsoft 365 tenant assessments need file repair, ones sent to my e-mail after completion as well as ones downloaded directly from sandbox - error message is

“We found a problem with some content in"filename.xlsx”. Do you want us to try to recover as much as we can? If you trust the source of this workbook, click Yes."

I click Yes, the dashboard tab is all zeros, but then I click on Enable Editing, and I get the following message:

Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.
Repaired Records: String properties from /xl/sharedStrings.xml part (Strings).

once editing is available, the Dashboard shows data, but not sure what else may have ended up being missing.
A log of the repairs is available.
