MAYTECH v2 remote, help with settings please

Hello,

i just connected everything. I have flispky motor 65161, FlipskyFSESC 200A 60V ESC base on VESC6 and maytech remote v2. I did motor and input setups in vesc tool according to their video, but my throttle is functioning from 60-100% of throttle only. Around 40 percents it makes sound, but not spin. Can you help please? I use 5.2 firmware, i already tried latest, but with the same problem.
