It's probably related to your first effort. Companion probably set up the folders then couldn't import into them. You may need to use a file manager to edit [remove] the files on the tablet if it is causing a problem. I think you'll find them in the [storage location] zubersoft.mspro >files folder. [Or something like that.]

As far as I could see, my effort with Companion didn't move anything to the tablet or create any directories.

Even if that had happened, these are the same files, i.e. just the title as the filename - I have never tried to transfer the files as originally named - so it doesn't really account for what actually happened.
