Tectonic Interactions Concerns/Questions

[Vallahd]

Hello,

I've been working on a 1.18.2 Minecraft pack, dropped Biomes O'Plenty for BYG, and been enjoying the world generation. However, there seems to be an issue somewhere. I'm not sure why, but I've had large swaths of land that are above the ocean, but are counted as ocean, deep ocean, cold ocean, etc. I've not seen this before with BOP and I know BYG has some custom terrain shaping. Is there anything I can do to make a compatibility config for this?

Also, pic for reference. Mind the siren.
