Altium Footprint using lines arcs and shapes
Start with "top layer" pads named 1 and 2, instead of through-hole pads like you have now.  The way your display settings are, it also looks like your through-holes are non-plated which would cause further problems obviously, given that it breaks up the traces.

Once those pads are placed, simply draw nets connected to the pads.  These nets should have "no net" properties.  

It should look something like this:


One final thought, you'll want to make sure that you've drawn soldermask all over the part where the carbon pill will be pressed, otherwise your button won't work.  It's hard to tell if you are missing this or just not drawing that layer.  

I've also attached a .PcbLib with just an Abatek silicone membrane footprint in there that you can copy and modify if that helps you.
