Ive never done this before so sorry for lack of formatting but ive been using RLcraft modpack and i installed Applied Energistics 2 or 1.12.2 stable build. I followed multiple storage systems step by step but i cant put items inside the terminal, ive tried shift-clicking and other ways but it never works. so i would like to know if i'm doing something wrong or its a complication between mods.

Thanks for reading this any help is appreciated.
As a last ditch effort i tried one more time and it worked magically so issue resolved
