The issue comes from the auto detect function, which detects both old and new locations, yielding to 2 distinct paths in the configuration.
I suspect that you seek for history files at the old location and if you find any, the path is added, and then proceed to the new location.
I do not transfer processed files because I have had issues in the past, such as losing files and was happy to recover them because there are rooms, such as PS, which are unable to send back history files in a proper format.
So I suppose that if I would clean the former history directory, it would not be detected and hence I would get a single location and no error, right?
