Scroll rect scrolling too fast causes problems

so i have a scroll rect and i wanted to be able to do circular scrolling (when elements leaves the screen from the top they go back to the bottom to reappear if the user continues scrolling)
so whenever a button leaves the top of the screen i move it manually to the bottom of the screen which works fine when i'm scrolling slowly but when i scroll fast the buttons positions gets all messed up the spaces between them gets messed up
