Back button loops pages

[Darryl D.]

When I go back (the browser back or the ionic back) the pages just loops between the last page and the current.

If I progress through 6 pages and then press back, it will just loop between the 6th and 5th.

I have a repo where its happening

Any idea what could be causing this? I'm kinda stumped at this point.
