Vtol 4.4 - q hover alt hold problem

Hello everyone,
I have 2.5 Meter VTOL with X frame and I have issue with the alt hold on quad modes I get 3-4 meters up and downs with no stick commands,
And some times doesn’t listen to the throttle untill I take it to qstabilise
I have tried to follow the documents of the vtol and changes the parameters as the suggested but with no success,

Baro alt vs ch3 throttle
