Hi Jabez Dupreez,
Thanks for the updates, as for the issue, to check if the issue is related to Office cached files, I would suggest you File > Open > Files Needing Attention to check if you have any files listed here, if you get any files, please resolve these files by save a copy or discard changes. Then go to File> Options> Save> Cache Settings, Select Delete cached files. Then restart your PC, reopen the file from SharePoint and check the result.
If suggestion above doesn’t help, may I know does the issue happen if you open other workbooks in the library? what if you open workbooks from other libraries? Does the same issue happen?
Regards,
Clark
