The name of the page can be whatever you like, it does not invoke the services page template. Selecting it from the dropdown sets the page template. There’s nothing specific to Moesia here.
Only thing you need is to change the page slug, because yoursite.com/services will point to the Services custom post type archive, not to your actual page. Same goes for every other CPT.
So you can name your page Services and that will be the title displayed on your page, but make sure the URL is something like: yoursite.com/my-services or yoursite.com/services-page or whatever you want, just don’t let it be yoursite.com/services.
