Custom Post Type link

Hi there,

I have a question for you! So I use my own Custom Post Types, one called “Services”, within this CPT there are posts like “Design”, “Development” and such.

My page queries the posts in the Services CPT and has a template name. So the breadcrumb is now:
Home -> Services

When I go to a service, the breadcrumb will be:
Home -> Services -> Design

All’s fine, but when I want to go back and click on Services in the breadcrumb, the link is:

https://blabla/?post_type=services

Is there any way to change the ?post_type=services to just the page id.

Off (offtopic), do you know how to style the ?post_type=services page? ??
