Poison arrows and explosive arrows acting buggy

Anyone notice that when you fire a poison arrow at the flames produced by an explosive jar they don’t ignite into a mushroom cloud flame anymore? Is this intended or a bug? Also, Ive noticed that if you put explosive arrows and poison arrows in your quick bar only the poison arrows work. The explosive arrows will just do the bow draw animation but no arrow is fired. If i equip explosive arrows from the inventory they fire normally.

I would call “poison causes a mushroom explosion” a bug…

It still does it when you use it in combo with explosive arrows though.
