Loot problems letting me roll?

So i joined a heroic Aberrus and loot box would show up and let me roll on items i could use etc. fine no problems. Problem is i joined a Normal Abberus and the loot box would show up and i could not roll or cancel etc at all and it would just sit there in the loot box saying its waiting for me to roll yet i cannot. Even when i click the boss i see the loot yet cant do anything.

Anyone haveing a problem with this?
