nord piano 3 key too noisy when releasing

[NikoSoung]

Hello everyone,
I just want to know if this phenomenon is common, when I release some keys rapidly, there’s a noisy sound going on, it sounds like two plastic things rubbing together, really noisy. I uploaded a video, link below:

Thanks if you can tell me if it’s normal and if not what I should do

Doesn't sound normal to me, I have the ne5 hp, and the hp keybeds are known to be noisier than the HA keybeds. It has been noisy but not at all what yours is sounding like.
