First person hud does not show up when cast to it unless it has been opened (MAC)

If the user tries to cast to the First person HUD before the blueprint has ever been opened it will not show up on the list.

1. Open the a first person template on a MAC
2. Create a new Actor blueprint
3. Try to cast to the First Person HUD blueprint
   Player controller > Get HUD > Cast to First person HUD
4. Notice that the First person hud blueprint does not come up as an option
5. Open the First person HUD blueprint
6. Go back to the actor that was created
7. Try to cast to the First Person HUD blueprint
   Player controller > Get HUD > Cast to First person HUD
8. Notice that now the First person HUD comes up as an option

Why doesn't this cast work, until I look at the BP I am trying to cast to?
