Sinclair ult stealing cancellation keybind bug

[Hae]

When stealing certain heroes ults, the cancellation button is different for all of them. I have my ult to "caps lock" and cancellation button is "G". When I steal Mcginnis ult, I cannot cancel with "G" but with Bebops, I can cancel with "G". With Seven I cannot cancel with "G" and with Grey Talon, the ult says "Press caps lock" to detonate, but I have to press "G". Caps lock does not work.
