The grand 2/ The Grand 3 Sustain Pedal Help

This question is actually for The Grand 2 which I am using. Whenever I press the sustain pedal on my piano the note e5 is pressed on The Grand 2 and instead of behaving like a sustain pedal it toggles on and off very oddly. All three of my pedals behave in the same fashion. How do I fix this!? I can’t find much online.

I have a kawai ce200 digital piano.

I have used fl studio, kontakt and other midi softwares and the same thing keeps happening. Each time I press my sustain pedal the note e5 is pressed and sustain toggles on and off.

Any help appreciated or pointing me in the right direction.
