Holograms not appearing in 1.17

[Shanman150]

We launched our summer server in 1.17 and went back to use our favorite shop plugin, ShopChest. It's still got all the functionality, but probably due to the new items, the holograms are missing. I've got signs up designating what each shop sells, but are there plans to fix the hologram issue? (Or is the hologram issue on my side?)
