Describe the bug
Setting ControlNether to false does not disable BYG nether biomes

To Reproduce
Set ControlNether to false, make new world, go to nether

Expected behavior
For it to not have BYG nether biomes

Screenshots/Videos

From my modpack

From an instance with only BYG

Logs
My modpack:
latest.log
Github isn't letting my upload debug.log
New instance with only BYG and identical config:
latest.log
debug.log

Setting NetherBiomeSize = 0 also did not work:

This is a new world made after a restart, after changing that config.

WAIT

THERE'S TWO controlNetherS!

I'll try regenning the config, see if it gens back with 2.

Ok so, regenning it only left me with one controlNether. I have no idea how that would have happened. Setting that to false now and making a new world...

Yep. That worked. I have no idea what the hell could have caused that. Sorry all!
