Pro sites working one moment then not giving strange checkout urls

When clicking select theme it brings me to pro sites page, the url once it gets to the pro-sites page is:

https://mynetwork.com/pro-site/?dm=bypass&blog_template=10&action=new_blog

Not sure why: dm=bypass is in the url

When the gateway is shown stipe, the form action the action go to:

https://mynetwork.com/?preview=true&page_id=59&dm=bypass

Any idea how this could all the sudden start happening? I have been messing with prosites but never seening this before? Perhaps the dev can chime in
