From CurseForge:

I love this mod, however I have noticed that it interferes with particle effects. Any block that is a part of the multi block kitchen (primarily the oven) will cause any particles to not render. I loaded the mod by itself to test and any block that gives off particles within a 64 block radius of the kitchen blocks will not render unless looking east or directly up at the sky. I built a home with a campfire chimney so the smoke would come out the top and when building a kitchen within the same home I noticed that the campfire stopped giving off particles, along with any other blocks that give off particles.

Same here. latest version for 1.15.2. And it isn't so much that they don't render. They don't generate. If the player gets close enough to the multiblock kitchen new particles stop being generated, but already existing particles are still visible.
