Rekordbox 4.2.1 Change List name

if I change a list name (also in a folder!) the older list with the old name is after a sync on the ssd or stick. i have to go to the ssd/stick and have to delete the list by hand in rekordbox... or have to delete it on the xdj-rx - please check this! if you have a lot of lists and folders you run out of conrtol on the ssd/stick !!! thx
