Mangroove planks aren't compatible

So, when I dont have much wood left and have to use various of different wood, mangroove wont combine with other woods to make what I want, for example, I want a bed from one mangroove plank and 2 oak planks and it doesn't work, but it works for 1 spruce plank and 2 oaks and other types of wood. I think this is a minor issue but it would be nice to have.
