Word file quick parts don't match correctly to SharePoint lists just shows numbers

I am able to create new documents and rename them or change their codes without encountering any issues. I can even duplicate data from documents with broken quickparts into unnamed documents and have functional quick parts in these documents with the same text data. However, after deleting the original document and renaming the new document with the same name to replace the old one thinking its fixed, the quick parts in the new document stop working. This makes me suspect that SharePoint is altering the document based on cached information that I am unable to locate.

Although most documents are unaffected, this issue seems to occur at random. Again if I replace a broken quick part document with a working one and redo it from scratch, the quick parts are fine initially, but as soon as I rename the new file with the file name of the previously deleted one with the quick part issue, the new file becomes broken as well. This occurs even though I may be the only one accessing the files and no automation processes are involved, these files just have text and maybe a table or some images, they are not complex or even large.

The only solution seems to be when this issue occurs is to create a new duplicate document from scratch and give it a different name. Although this interferes with our indexing and naming system.

Reinserting a quick part from the fields section doesn't fix it either.

Surely there is a better fix or a way to resolve this properly.
