LFO value changing at playback - resets itself to -96

i have an lfo changing the pitch (voice transpose) with a value of +2. It was working totally fine for the past few weeks.

Now it resets the value permanatly to -96 which i can manually change, but everytime i try to make a change it resets again.

any help would be apreciated

Right click on the pitch value and press clear MIDI learn
