My excel document properties keep reverting when I save the file

I am getting a similar issue with some excel and powerpoint files but only a certain value will not update, the rest of the values remain as I set them and do not revert. I have tried all the suggestions found in the community: remove the custom xml, dump the cache, delete and reload the file. Nothing works. However, I found that the missing sharepoint data is there and can viewed in the file properties within the app, it is just not showing in the metadata column in the sharepoint library and I am not rebuilding that column with 1000s of documents to redo.
