It looks like you did everything correctly except for the amount of oil that you’re supposed to put in there. The bubble does need to be smaller because when you’re moving it up and down the oil is acting as a border/wall when it needs to be flowing. Also! Maybe try using baby oil, cuticle oils can sometimes have hydrating products in it which causes it to flow incorrectly :)
