The Bug
Azalea trees can fail to generate leaving only rooted dirt
Reproduce
Seed: 2407063674254264572
Coordinates: /execute in minecraft:overworld run tp @s 19334.44 72.65 2083.74 334.20 69.30
Expected Result
The Azalea tree wouldn't fail to generate and find a valid location to generate at
Is it possible that the azalea tree generated on top of the jungle tree, or did you find it also out of jungle biomes/with no trees nearby?
