EE 2.9.0
I'm attempting to set up a template route for a new section of the site I'm working on. However when I do I get the error: Template Route Already in use
I've set up a route for the blog/single template which works /blog/{blog-post:alpha_dash}
However when I try to set one of up for about/single /about/news/{news-post:alpha_dash}
The CP highlights both the blog and about/single template and says Route Already in use. Also won't let me set segment required on the about route.
When I refresh the page the blog route is there, but the about route is gone. See attached screenshot.
