Negated parts duplicated in water terrain?

I was building until I realized this happened on my water terrain.


There are lots of red cylinders on the water terrain, which is the same part I used to negate a part on a union.

Is there any way to fix this?
This problem is completely new to me.

Delete the extra negative parts? Not really sure what else to say. Check above and below that general area to see if they’re there, and delete them. Or if you still need them, just anchor them. (Select the part, open Properties in the View tab, and check the “Anchored” button.)

I made sure the whole workspace was anchored yet it still happened anyway, I cant find any other post or player that has had this same problem.

as it turns out, one of my instance part scripts went all wonky, because I forgot to anchor them.
