Mastery rank 28 test bugged - can't throw canister with melee equipped

[Larsurus]

There's a bug in mastery rank 28 test where if you pick up the canister and use quick melee you can't throw the canister unless you switch back to your ranged weapon. Reproducable.

I can confirm that Mastery Rank 28 practice and official tests are bugged. After throwing canisters I can't do no damage to enemies. Kill count stays at 0. Enemies are not dying. Canisters have no affect on them. I tried some of the suggestion from this link with no luck.
