Potion variations won't work

I made a mod that adds a few potions with special effects, but the variations (lingering, splash, and arrow) do not cause the effect to take place, one of the effects is warp which is just chorus fruit in potion form, but it doesn't seem to warp when used as lingering, splash, or arrow, but works perfectly fine with drinking, samething with a combustion potion I made, and these potions were made with those effects in mind.
