New player... Bash issue?

[Arishkogol]

Hi, I'm a new (returning) player. Name's Arishkogol, how do you do?

Anywho, I reached level 6 on my SK and was eager to use my new Bash skill, except that while it's on my hotbar, it's absent from my skills list and actions bar (previously it was there and said "level 6").

I did do a stupid and die right after hitting level 6, thus making me level 5 for a short bit, but does anyone know what's going on? Am I just being dumb and missing something?

Thanks for any input!
