using the skyblock nether star right click on player does not work with this modpack

Hey

When I use the nether star to right click on a player to see what armour they are using it does not work and goes straight to the to the skyblock menu when I am using this modpack. I am sure others would also like this feature available in conjunction with is useful modpack. 

I don't know which mod in this modpack is the problem, 

Please fix. Thank you. :)
