Alright... Im actually a pretty smart guy, but for the life of me I cant figure out the trick to linking a spell to a particular hand. For example when I select a spell a litle Icon appears that says L LR or R. Clearly that means left, right or left and right. So why is it that when I use the left mouse button it sometimes links it to the right hand thereby un-equipping my weapon or trying to connect a spell to my right hand by using the right mouse button it cycles through L and LR but wont cycle to R? Or any variation of this....

Does this make sense?

Im on a PC

I'm on Xbox so I don't have this problem. Maybe map your buttons differently?

Yes it makes sense.
Traditionally for games weapons are wielded in the right hand, shields in the left hand. And the mouse triggers the weapon arm on mouse left, the shield on mouse right. Simply because the players are used to that.

So either u can redo the key mapping to right mouse click -> right hand and left mouse click -> left hand ore just think of this behavior.
