Dark Forest Mushrooms not converting to dynamic tree+ mushrooms

[thatsacat]

It seems that not all mushrooms in the dark forest biome are being converted into dynamic trees+ mushroom counterparts
NeoForge Version 21.1.211
Dynamic Trees Version 1.5.0
Dynamic Trees+ Version 1.3.0

This was tested on a instance using only DT and DT+

I have seen the same, occurs with just DT and DT+ and with other mods affecting worldgen.
