Sections not listed in drop down list for sections to link to

I am just trying to add a link from the purple ‘My Services’ button down to the services section below. I have added the ID ‘ServicesSection’, but the only ones that are showing are ‘email-2’, ‘email-form-2’ and ‘name-2’ (Twice each). What am I missing? Thank you!
