On our JIRA service desk channel portal, we are getting different URL which redirects to same page with a slight different design. Following is a snap of breadcrumb on our service desk portal:

Service desk has created two URLs for same page(OS Help Desk/OS Help Desk). Both have same content with slight different design and an additional /2 added to the URL.
As it is quite misleading to our users, we would like to have only one URL on the breadcrumb. How this can be achieved?
