So I just installed your mod in my modpack but when i load it on the client side notice I can't see my chest i placed also the cant see item that is dropped.

without mod on client

with mod on client
UMMMMM
OK as I was doing this I just re-enabled the mod and not it works betting. Im going to test it more but strange though

This mod should have nothing to do with your issue; I'd look into your other mods. It only changes what item is dropped by the composter.
