thats just how structures work

https://github.com/FinnSetchell/MoogsVoyagerStructures/blob/1.20-MultiLoader/common/src/main/resources/data/mvs/worldgen/structure/other_decoration/mine_with_campsite.json

you can try setting

  "terrain_height_radius_check": 1,
  "allowed_terrain_height_range": 3,

and play around with allowed_terrain_height_range
the radius check 1 means it checks 9 chunks (structure placement and the chunks around it) so i'd recommend not increasing it

having too low values can make the structure pretty somewhat rare though

This happens with other structures within the mod as well.
