semi-pistol cannonade does not work on the secondary sporelacer kitgun

[Bemen_82]

Hi

my secondary kitgun is made from [sporelacer, haymaker, splat] parts.

The problem is when I put [semi-pistol cannonade] on my kitgun (which is semi trigger) it does not change any stats like adding damage [300%], or the punch through [1.5], nor does it lock the fire rate.

And when I close the weapon modding screen and re-open it, it automatically removes it from the weapon.
