It's actually the Infuse icon/function that breaks the perk display. Leave the Vault, then re-enter. All functionality will work fine until you hover over Infuse. Then every Vault item starts to misbehave to a point where there is no UI but only the graphics of the weapon shown.
As long as you don't hover over it, at least you can do the rest in the mean time. Infusion has to be done in inventory meanwhile til this bug is fixed (hopefully soon).
