I've not known cars to ever have two choke systems, would have thought the auto would have been disconnected when the "Manuel" system was fitted or vice versa. If its manual get someone to operate it and see if the mechanism on the carburetor is returning to its off position fully,if not try to see why its stuck, perhaps cable has run out of travel or is adjusted incorrectly,or could be dry and siezed, if its siezed try WD40 and work it till it frees off,auto will be more difficult to check.
