Recently migrated my Plex configs, DBs, and meta data to another dedicated SSD as it was taking up all my cache space. Next came this same warning from FixCommonProblems plugin "...has volumes being passed that are mounted by Unassigned Devices, but they are not mounted with the slave option".
Problem is, the path in question is defined by AppData Config Path in the Docker Template ... and there does not appear to be a way to add the RW/Slave option (see screenshot).
How can I resolve this?
