Vikings control bug

i should be able to switch between vikings using numbers, in my case its 2 for olaf, 3 for baelog 4 for eric and 5 to select em all.
but for unknown reason only 5 is active and working, and the rest i can only click with mouse.

on other heroes everething is ok, bone armor on xul activating on 2 as i binded it.

i dont know how to attach pictures here and i dont really want to do anything, i just want to play some vikings and i need help. but apparently i cant contact support with this topic, so here we are.
