Gravimag prevents Focus gain in Archwing Missions?

[Katinka]

Maybe I'm missing something here but, 191 kills and only 11 melee kills so 180 ranged kills (no power kills with Amesha) plus there should have been shared exp from the three objectives and completion of Swordsman going through the Unairu lens on my Imperator Vandal. 
The Vazarin lens on Amesha and the Naramon lens on Kaszas worked fine but the Imperator Vandal looks to be broken and, unless I'm missing something, I'm going to guess it's because it has a Gravimag installed.

Edit:  Focus gain is working in non-archwing missions where I can use the weapon because of it's Gravimag.  It's just Archwing missions where it's not working.
