flicker strike targets vine arrow and toxic growth instead of enemy mobs

My friend and I party as duo. He is playing Pathfinder and I am playing Flicker Strike Chayula Monk. The problem is that flicker strike targets vine arrow and toxic growth plants instead of enemy mobs or boss.

Basically as a flicker strike monk, it's unplayable in parties where there is a bow user who uses mentioned skills. Please fix this problem. I searched google and I haven't found a bug report about this weird interaction. So I hope you'll fix it soon.
