Having some problems with vampire form on the PC.

I cant seem to exit vampire lord form. Im told to use the magic menu to exit it. However pressing TAB dont get me to the usual "Choose magic/perks, etc" menu but rather takes me straight to the vampire perk tree.

Z is the power skills which uses special powers. So I thought I could press it again to exit the form, but the Z is replaced in vampire lord form - causing you to use some bat teleport skill.

Any ideas on what to do?

In the favorites menu, there is an option to revert form. Use it just like any other power.

In my game is the Q key,
