Describe the Bug

I´m injecting a "catch-all" route [...slug] inside a custom integration. When doing this all other routes I create inside my pages folder can not be found.
I guess something is wrong in the prioritisation.

I´m willing to help fix this if someone can point me to the right direction in code.
