Weapon swap unassigns and moves skills

I could not find any existing thread about this.

I'm playing a Dualist and have a two handed axe and bow equipped.

When swapping between the two weapon sets the skills associated with primary and second attack for each weapon set is unassigned. This is quite a bother.

Also the swapping seems to mix up the keyboard assignments as well. As opposed to the mouse assignments mentioned above.

I would expect at least the mouse button assignments to be persisted for the weapons set.
ie. For my axe the primary attack is lightning strike.
I switch to bow and attack with poison arrow with same mouse button (left) and then switch back to axe and do a lightning attack again.

I have the same problem with my ranger char. Switching between bow and melee disables attacs assigned to LM. It´s quite a minor bug, but it should be fixed...

Same thing, even if I'm using the same class of weapons. I'm using auras on all my 2nd weapon skills so I can easily switch back and forth. I usually end up losing a skill or 2 when I switch back.
