GAMEPLAY Self Cast Mikaels

So i use my trinkit on number 5 instead of 4 and put mikaels Crucible on number 4 cuz i prefer it there for since it is an active item .. well it works fine until i want to use ALT 4 to cast on myself it doesnt work i have to use ALT 5 to cast it on myself for whatever reason dont know why but its annoying so RIOT please fix this so i can self cast it on the number that i have it on and dont die when i coulda cleansed and lived
