Document Properties/Metadata being removed SharePoint Online

[Nicolle Brice]

Hi we have a situation where metadata is being blanked.  We don't know why.  Issue seems to be related to QuickEdit view.  Administrators edit metadata in QuickEdit mode, then all of a sudden it is stripped for other documents.  Also, sometimes the version time is showing a US timezone (not Australia).  I am unable to replicate but our HR team are consistently replicating the issue.  Has anyone experienced the same?

@Nicolle Brice Can you help me with what is the type of the field where data is going away.

@Vikram_Samal was various  column types.   I built a new library with the same metadata and used ShareGate to migrate the documents.  The new library is fine.  I don't know what caused the issue on the original library.
