I am building a level. the slopes i put in the level act weird. they dont get greeneed (sorry for bad english) when chosen and they dont get a color. Slopes i had put in the past act normal. the back then slope was copy-pasted and works normally. It is a nine circles themed level so i cant copy-paste the slope objects. the same happens on a regular sized same type slope, but doesent happen in a white block

(couldnt upload the video, i will upload as soon as i can)

Edit: it wont upload, i even compressed and cut it as much as i can. WHY CANT IT UPLOAD 8MB??????!!!!!!!!!
