As the default slider in the theme only allows the page selection options to be displayed in the featured slider, the functionality you are looking for is not available in the theme correctly.
Furthermore, as per theme’s home page layout options, Either widget area or the Front page sections can be used to display the front page. So both the services section and the Slider is not displayed in the front page.
Also, with your query it is also not quite clear if you want to link to the same page or to the post page you have selected for the services section. Please explain us your exact requirements so that we could suggest you further resolutions.
