What you are describing is a side effect of the change:
Removed non-capital skill requirements from capital remote assistance modules. (Shield Emission Systems, Energy Emission Systems, Remote Hull Repair Systems and Remote Armor Repair Systems)
We are currently in the process of refactoring the way skills and effects apply to capital modules.
In this case the gang links had previously been affecting Capital Remote Armor Repair Systems but not Capital Shield Transporters. This change brought the armor reps in line with the shield variants.
We may re-evaluate this going forward, either through changes to the gang boost modules or possibly to the triage mod, but we can't guarantee anything at this point.
