loot table not working with other mod

Hi there !

My mod have a loot table for the vanilla grass. It works perfectly fine but as soon as I add an other mod in my instance, the loot table stop working...

Even if the other mod is related to performance like Rubidium / occulus or any kind of mod which are not even related to blocks, grass or whatever.

So what could be the reason for a loot table to get overrided by the vanilla one ? 

Thanks in advance for your advices
