Mangrove wood generate less while Mangrove leaves generate abundantly when growing a Mangrove Tree

While I was growing and bonemealing propagules, the tree that generated either has 1-6 logs or just leaves and no logs at all to get. This is annoying when you think about it because you get less or non at all from the tree which makes planting them useless for wood gathering. The tree should have branches like the acacia and the logs be as tall as the tallest 1 thick tree.
