Can't Disable A Lot of Monuments

I unloaded the plugin and set Coastal Monuments to not auto spawn:

  "Coastal Monuments": {
    "Allow automatic spawn? [true/false]": false,

That section has 3 locations:

strandedbarge

pirs

submarine

I set all 3 locations to:

"Allow automatic spawn? [true/false]": false,

The very first thing to spawn was the submarine. Why, if I have all of those settings set to false would the submarine still spawn? The same was true for the Water Monuments where The Broken Giant would spawn even though it was disabled.
