Specific montage can't be played via BP call

Hi, everyone

We’ve encountered a situation where we can’t play the specific anim montage via simple keypress or event. It’s the one from Kubold’s cover set - going from idle to cover. Other montages can be played (reload, weapon switch, etc.). We’ve created it out of anim sequence, made sure that final pose is connected to state machine and still nothing. Then we’ve tried connecting keypress node directly to anim montage play and still nothing

Can you please point me to what we’re doing wrong? Or maybe a cover system should not use montages and use states transitions instead?
