Labeling by MCAS modifies document metadata and creates new version

[Nicolas69]

Dear community,

I'm currently working for a client, where automatic labeling by MCAS is in place. What I see now is, that labeled documents are modified by "SharePoint App", and a new version is created. This is very confusing for the user, as it breaks the "user" history:

Is this expected behavior?

Thx

Is integration with AIP enabled?

Does the label configuration within AIP have the "Preserve "Date modified", "Last modified" and "Modified by":" enabled?

Thanks for the reply @vidrine_ 

Yes, option is enabled.

Let me precise: That behavior only happens in SharePoint Online, when applying labels to on-prem documents through scanner, metadata remains as expected.
