Weird Biome Collision

I hope this hasn't been reported but I found this weird biome thing (pic below).
What is happening is the wooded badlands plateau (because those trees on the top are supposed to be there) is merging with the river biome, and for some reason when I went over the grass, the biome showed as minecraft:river.
The seed is 6959506661658038163 and the coordinates of the photo is x=-11 y=91 z=2
There are no steps to reproduce because this is spawn and it looks weird.
Oh, also, the badlands to the right is the eroded badlands, not the other kind.
