Why don't Bound Arrows show up when I use the Bound Bow spell?

I was told in the past that when you cast the Bound Bow spell and have no arrows, the game spawns 100 Bound Arrows and equips them so you can actually use the bow. However, every time I’ve cast the spell (with or without arrows in my inventory) they never equip. I’ve seen them show up in my inventory via console and even equipped them with console but they don’t do it on their own. And being bound weapons from a spell, they also don’t show up in my inventory (well they do in the console window but not in the actual "player facing" inventory). Is there any way to fix this? Also why does this happen in the first place?
