Are you using this on a nikon camera if so the iris ring may have moved you need to move the ring to the red number you will see a bump on the iris ring there is a swich you slide to see a orange dot this will lock the iris ring
Hi This is on a nikon i hope the iris ring may have moved it must be on the red number
It sounds that the iris ring has moved of the red auto
setting just turn the ring to the red mark and see
