Cannot Hotbar skills

[Distance]

Hey,

I've been having issues where I unlock skills but I can't use them OR hotbar them. Do I have to keep resetting my skills and wasting gold in hopes that it doesn't bug? Is this a common issue?

Skills currently affected: Berserk - Starfall


Note: Berserk used to work, but I respec'd as feral tank and now it doesn't work.



EDIT: I can work around this by writing cast macros for the skills. Would still like to know if this is a known bug.
