I have found the answer to part of my problem, Meta Blocks take up all the space and cause the "in the way" pop up. However still not sure how to make the loot randomizers trigger and run so they can be cleared away and actually work. Also is there a way to run a command to clear a type of block that I'm unaware of?

So I have been trying to spawn in a ruin to fix up in survival however after it's spawned in, whenever I go to place blocks I get the something is in the way pop up. The crates/chests also keep their randomizers and I've already tried relogging. Is there a way to fix this at all?
