Hi,
I just boought GSB2 for Windows from Steam.
In the weapon list available in the ship design for cruiser/dread, there are two weapons called “Pulse Cannon” with different stats.
I enclosed a couple of snapshots.
I guess that one of them has the wrong name! 
edit:
In an old post Joecairo already noticed it
