Can't remove Frozen Shelter while using Ice Beam as Kelvin

[raptor777777]

Alright, if I use Frozen Shelter, then Ice Beam, then I can't cancel Frozen Shelter until Ice Beam either finishes or is cancelled first. I'm hammering 4 like crazy but my Frozen Shelter isn't disappearing.

Easily replicable by switching to Kelvin in the hideout, pressing 4 for Frozen Shelter, then pressing 3 for Ice Beam, then hitting 4 to try to cancel Frozen Shelter.
