Issues with powered armor (likely user error)

[SnowHeart]

All,

I'm having some continuing issues on how to figure out the use of powered armor in Hero Lab. In terms of context, I have a goblin running Ironclad Bulwark. A relevant portion of the rules seems to be:

"Mounted weapons designed for a creature the size of the powered armor or smaller impose no penalty to attack rolls."

Yet, when I mount a medium or small weapon on the armor, there is a significant penalty on the attack roll.

A second issue I'm having is that, while I can unmount a weapon from powered armor, there doesn't seem to be any way to mount it once it's in my character's general inventory. As a workaround, I'm thinking of just creating a generic container called "Mounted Weapons" and move things in or out of that as needed.

Thoughts?
