Troubleshooting Changed Cap Weapon bug

Ive having issues when i send my modified Kol into combat, whether it be to clear local militias at planets or enemy fleets, the kol attacks and doesnt ever finish them off. It attacks the target until its down to 1-4% of its HP and then switches, essentially presuming its been destroyed. I changed the lasers to autocannon class, fires to projectiles and has the gauss defense platform muzzle, projectile and hit effects. Here is a sample of the changes: Note, this isnt the exact copy since its on my gaming desktop and im on my laptop.
