Bug in the Jungle, Voli in the jungle doing Blue Golem in bush

Hello, here is a bug I have notice for a long time wich seems to only happen on Voli. When I try to tank blue in the bush It always seems to bug, blue Golem starts to go back and fourth on himself and I have trouble targetting him. This does not seem likes its intented to do this since it only happens on voli and I can do this with any other jungler. This seems to only happen as voli in the jungle on a summoners rift. Please check this out. Thanks.
