Mercenary Crossbow shot bugged? Can't use second crossbow.

I'm trying to use two crossbows with different affixes but every time I switch to the second and load a shell to fire it switches back to the first before firing when I left click.

I've tried messing around with the left click abilities but setting it to basic bolt loads basic built but doesn't fire when I left click. Pick crossbow shot then only fires that one crossbow and when I try to switch away from it switches back before firing.

I have no idea what I'm doing wrong.

Have same issue, can't understand what I'm doing wrong. Just wanted to experiment with crossbows

UPD: Okay, I get it. When you equip one more crossbow, you have one more skill option called "Crossbow shot" insted of "Punch". You just need to bind one "Crossbow shot" for one key, and another crossbow's "Crossbow shot" to another key, for example one for m1 and second for m2, so when you choose which ammo type to shot, you also need to choose from which crossbow to shoot it. Hope it helps
