Explosive Shot Consuming Fully Broken Armour

I am using explosive shot on my mercenary character as the main damage dealer. By utilizing gas grenades and the support that breaks armour based on poison damage, I fully break the target's armour. However my first shot of explosive shot consumes the broken armour despite not having exploit weakness support socketed.

This is an issue because I specced into the wheel that makes fully broken armour apply to fire damage. I only get 1 shot in before it takes another 8 seconds of so of waiting for it to fully break again.

None of my supports on any gem consume broken armour, and none of the skills I am utilizing say they consume broken armour.

BUMP
Have same problem

I have the same problem though i use armour piercing rounds to break the armour and I also tried to remove every support from explosive shot and it still consumes the fully broken armour. I also tried using exploding grenade to see if it was because of the explosion for some reason but it only gets consumed by explosive shot.

BUMP same issue here literally can't play mortar totems with armour break because of this. Crappy no dmg explosive shot is consuming the break so I can't deal extra damage.

BUMP same issue with explosive shot, mortars and armour break
