4iiii power meter showing power when not pedaling

I’m having an issue with the trainer day app showing power when I’m clearly not pedaling. Sometimes its 14W sometimes even 80 watts.

It works fine when I continue pedaling but it never shows 0. Its not the power meter because I user another app and it shows zero when I stop pedaling.

When I use my indoor trainer and power tap pedals p1, it works perfectly.

Go to other settings and turn off power smoothing. Should fix it.
