[GAMEPLAY] A Screw up on build pathing?

So my friend noted me a few days ago (like 2-3 days ago) this little screw up it seems that riot forgot to remove or fix, no clue which.

If you select the item , options pop up at the top for you on what you can build that into, one of them is but once you select , you can see that you can build into when the item's crafting doesn't need anymore after the change to it. (which is + + now)

is there any reason why this is still in the game? just got on to check if it was still there and can confirm its still sitting there.
