Modded items not appearing in creative inventory

[unknownoddity]

I am trying to play on a dedicated server with the modpack all the lucky blocks 2.0 from the Technic launcher and when i load in the only way to give myself the modded items is by using the /give command and of course this is kinda annoying so i am wondering if there is a well know fix for this? oh and i forgot to mention i there is no visible errors in the logs but i will post my latest anyway just incase as it did crash a few times when i was trying some things.
