Pixelmon Mod

I've recently been playing pixelmon 8.2 and for some reason Jungle temples and Ocean monuments on spawning pokemon and I can't see an option for this in the config on the title screen, any help?

Structure spawns are a bit tricky due to how the spawnable area works. By default there is an 18 block radius around players that blocks spawns, to avoid dropping aggressive mons on them and remove the risk of having them pushed off ledges. But this also means that structures are very unlikely to spawn anything while you're in it.
