Current issue

Hi

I have an issue with

https://codepen.io/AYling/pen/pGLPBv

See the Pen Pauls Infoshot by Paul (@AYling) on CodePen.

I am trying to get the output into this format

as opposed to the current output that looks like this

So For example
I need the header "General Resources" to appear once ONLY and above the two items (that are both hyperlinks) called Overview of Chiang Mia and Digital Nomad.
