Need to Know If Plasma gun and Volley Fire Bugged or Intended feature

When using the [Plasma Gun] you can reload, and it will get rid of [All Heat] currently in the gun . I tried using [volley Fire] with [Sustaining Fire] feat.
So when i use [volley fire] it will reload my plasma gun and will get rid of all built up heat.
Instead all it does is reloads the [ammo count] and [doesn’t] get rid of the heat.
I need to know if this is a bug or intended feature.

I reported it a while back. It got “acknowledged”.

Take that for what you want.
