Course Presentation (anchor)

Using the Anchor element to customise navigation in Course Presentation

I'm creating some  [Prev] [Resources] [Activity] [Next] type navigation using anchors. When I add an anchor in course presentation, giving it a title (e.g. like "Slide 20" or "Next"), should that title then appear as a label for the anchor?  For me it doesn't.  I'm working around by adding a text box over the anchor, and then bringing the anchor to the front.  This seems to work but is it necessary or am I missing something simple.

Thanks for any advice before I start doing the for all slides.... (using Moodle plugin)
