maybe a stupid question but you may see such on a regular basis in the near future from me

so, I've received my warthog hotas and wanted to fly around in dcs world a bit... downloaded polaris & schnix warthog profiles, loaded, done
but I just can't get those pedals working... when I start up vkb device config it's looking good (would be bit less confusing if the pedals themselves would show up but ok), pedals work on x-axis test and the joytester as well
at dcs world config the tiny box column is there (at first start up there where some auto-assigned "buttons" in that column although the peddals don't even have any

but here I'm just stuck... when I click into the column and hit axis assign after that ---> nothing
a double click brings up another menue but that doesn't seem to help either
stepping on the pedals (at any point) doesn't change anything
so, what am I doing wrong? other games (war thunder, rise of flight, arma 3) do react on inputs by the pedals but none of those I want to play

thanks for the help, appreciated!
regards,
AR
