Kalista Binding with Reddit Mou

So I recently tried playing Kalista , and she was pretty sick but there was just one problem, I couldn't bind with an Ally. This was because of my reddit-right click where both my mouse buttons pose as attack moves. I tried a bunch of different stuff, but at the end of the game I still hadn't binded with my ally. (Which also meant I couldn't use my ult).

Any suggestions on what to do?
