Cannot switch to DOH classes

[Golophei]

This is a new bug for me.

I logged into the game. Tried switching to my ALC class from MRD inside Market ward/jeweler. Got an error message saying "Unable to equip. Not enough action slot available" which prohibited me from switching.

I then tried to switch to all other DoH and DoL classes and still getting the very same error message. However, I have no problem at all to switch to any other DoM/W classes or any other weapons.

Later, I've tried unequipped all my armors and accessories. Still won't allow me to switch to any DoH or DoL classes. I also tried logging out from game into the character selection page and then logged right back in. Did not help either.

Right now, I have exited FFXIV completely and hoping it will finally solving this problem. I will update the status.
