using abilities switches my main/secondary weapon to the melee weapon

[THEvalrog]

as the title implies, when im playing with any frame, and im using my powers, suddenly when the abilitie casting finishes, im equiped with my melee weapon, even if i was using my main weapon before casting the ability.  this bug happens at random, but does happen very often.
