Terex Posi Track stuck in bucket curl, boom lifts when controller pushed into boom down

Hi. New member here. The bucket tilt on my 2018 R070T has locked up into full curl up. boom control was functioning but would actually lift the boom somewhat when dropping it down and had to bump the controller forward 6/8 times to get it to ratchet down. Right controller sits properly in middle float position. Left control functioning properly. Engine also bogged as if under load, fortunately got it to the trailer and boom down but curl stuck up no down function. Bucket returned down after sitting up overnight but immediately curled back up with a rough almost under load restart. Any thoughts? Joystick? Loader valve? Bad luck? TIA Tom
