Co-Authoring issues

Hello all!

So, i have a co-authored workbook that has the following issues, after editing by one or both (only 2) users.

"New version available..we cannot apply changes made by someone else, then the reopen or learn more tab.

File is stored on Onedrive and both machines are logged into office 365

The barcode column is a font that generates a barcode which is printed and applied to the item.

I am at a loss as to why this message keeps coming up as, I believe we are complying to MS requirements.

i have supplied an example.

Thanks in advance
