Umidi module not recognizing note priority setting changes thru Config app

I have a 2nd hand Umidi module and for some reason I can change all settings with the config app but when I try to change the note priority to (LAST) that change is not recognized on the Umid module.
Is this a bug or is my module possibly defective?
Would love to be able to use this module in (last) note mode.
Thanks for any advice
