Monk skill Fire Ally bug

While playing on my Monk using the Inna’s set for Mystic Ally, and reaching the Rift Guardian in Greater Rifts; I’ve Noticed that the Fire Ally’s Split ability causes the Fire Ally to circle around the boss but instead of hitting it like it should, the Split Fire Ally litterally just stands there and won’t exlode the way they’re coded to do. This is causing 4-6 minute boss fights and failure on Higher Level Greater Rifts. I’m on Xbox 1… To replicate the issue, just play a Monk, check and copy my gear and skill loadout. Jump right into a 120+ Greater Rift and when you reach the Boss (Rift Guardian) watch as the Fire Ally only targets add on mobs Summond by the Guadian and watch as it simply won’t hit The Rift Guardian at all… I have Recorded video and will upload it to YouTube once I figure out how to link Xbox recordings and try to post a link to provide proof.
