How to remove Angular JS Route "#_=_" when redirecting to application route (via rails)

I have a rails action that redirect to the root of my application but angular seems to add #_=_ to the route.

I can't see why this is being added. It doesn't cause any harm, but it doesn't look professional.

Wondering how I can avoid having this appended to the root.

Note: Only added after redirect. Visiting root directly does not append.
