HELP Rising Floor on Cell BUG

[Myst42]

I have weird auto-rising floor on a custom cell, I dont know why it happens nor how to stop it.

Anybody knows anything about this bug?

 

If I go directly to the cell on game start it looks fine, If I go to it after doing progress through a dungeon, as is intended in my mod design, the bug happens.

 

This is how it looks normally, how it should look, and what I find when I go directly to the cell

Playing the dungeon that leads to it, and getting to the end, makes me find it like this:
