Collective pitch lock and values doesnt work/behave strangely 2.5

hello there my first post here,

have an apm 2.5 with a trex 600 flybarless working on it for some weeks now and I have this unusual behaviour of H_SV_MAN value when being set to 2-3-4-5 acts like it is on 0. with 1 it works.

and I seem to have trobule with H_COL_MID value. it seems to be not doing anything…

has anyone encountered such problems? any idea why this is caused?

thanks for your responses
