Druid bars problem when in combat

[Triseult]

I searched this forum for advice, but couldn't find anyone with a similar problem...

I'm level 18. When I switch to Bear form, I see all my buttons correctly, including the ones on bars 2 and 3 correctly. (These are the bars where Enrage and Bash are, respectively.)

As soon as I enter combat, though, bars 2 and 3 disappear. I don't see Enrage and Bash anymore. BUT, the key binding still works, so I can press the key shortcuts and use these skills.

As soon as I exit combat, this becomes normal again.

Any insight or help on this? Thank you!!
