Removing MiniDungeon Protection Markers and Sail Messages

So i came across a neat looking Ship structure on a romp through a planet (im using FU and a good number of mods like it so im trying to sightsee all the randomly generated structures), and i decided why not make it a home. So i go and use /admin, and then /settileprotection 0 false, which promptly made the whole thing destructable.

The problem is, when you enter the area, you get a message from sail about how its a pirate ship and all, even though i killed all the pirates. So i go into debug and find these blue markers:



Turns out these are the boundaries for the mini dungeon which explains why the front end of the ship were destructable, even before clearing the dungeon. So i wanna know, how can you get rid of these, and if its in admin mode, what commands can you use?

 

The only mod that im using which affects generation is Frackin' universe
