Cannot delete files (Mountain Duck, Google Drive, macOS)

[dzg]

I've got these 2 files in my mounted google drive that cannot be deleted:

~/Library/Application\ Support/Mountain\ Duck/Volumes.noindex/z00.localized/My\ Drive/FileThis\ \(current\)/delete/a/b/.nfs.20051026.371e 
~/Library/Application\ Support/Mountain\ Duck/Volumes.noindex/z00.localized/My\ Drive/FileThis\ \(current\)//a/b/.nfs.20051025.371e

If I delete them, they just re-appear.

I had to delete from source at Google Drive.
