Cant apply anything to a prop

Hello I’m Sorry if this is in the wrong place but idk where to post this then

i recently made a base Adv duped it onto another server but now i cant apply materials,fading doors and color or anything please help

They probably disable those stools.
Talk to an administrator on the sever.

No i can use them on normal props on the server but when i paste this in from my singeplayer map (I used SO LONG TIME on it ) it doesent let me and if i place a prop behind one of the props of the dupe it shoots through the duped prop and applys it to the one behind
