The issue that I'm having is fortunately very, very easy to reproduce - which is why I included a video.
Before watching the video, let me describe the issue in detail.
The setup I have is, 1 is fire bolt, 2 is fast heal, 3 is my shield, 4 is my sword, 5 is my bow.
Simple enough.
Now when I just press 1, 1 or 2, 2.. normally both spells will come up in both hands, no problem. You'll see that in the video. Then I press 3 to get my shield and then 4 to get my sword; Again, no problems. However as you see in the video, when I have both my shield and my sword equip and then press for example: 2, 2 to put my fast heal in my left and right hand so I can quickly dual cast it (very important in the heat of battle), the right hand doesn't show up correctly.
Fortunately... the right hand functions as though it's there - at least for healing. When I use it for the fire bolt, it looks almost as though the fireball is coming out from below and behind me, instead of where it should be. Dual charged spells work fine though, they just show the left hand charging the spell and the right hand is still missing, but it's functionally correct.
Now if I have a spell in both hands, right hand missing and I switch the left hand with a spell, the right hand does show up again. The only time the right hand disappears is when I go to dual wielding the same spell in both hands, from a left hand shield, right hand sword.
Here's the video:
