Infernalist Hellhound Bugs with Demon Form

When I talent into Hellhound with my Demon Form based build and activate Demon Form, the Hellhound dies/despawns and only comes back as soon as Demon Form is deactivated. It doesnt make a difference for me if I talent into Mastered Darkness for 10 Demonflame stack cap or not. Ive read on a thread Players had the issue only when Players are using Controller on PC, for me it didnt work either first until i Pressed Demon form first then pressed G then manually deactivated Hellhound and activated it. After that i could go in and out of Demon form without the Dog going away, however the Basic Attack information Panel Flicks Back to General Spell information when in Demon Form after gaining a Stack of Demon Flame.
Once I "debugged" the Hellhound with Mouse and Keyboard i can use it on Controller, the process didnt work on Controller at first to Debugg it, however the Hellhound Spell is now Duplicated in the Spell Pannel on Controller. Seems to be only visual since support gems socketed are shown in both.
