how to automatically count location instances

I am working on a class project for GD&T and cannot get the instances of a dimension to add up, which means I have to manually write it in the drawing. The solidworks help says to highlight the dimensions, right click, select "combine dimensions."

However, I never get the option to combine as that selection is not in the menu.

When I make the drawing, the instance count does not always show up, and the GD&T FCF has to be manually inserted. Again...

My goal is to have the hole instances count and the location instances count. The point is not for a work around. It should count instances automatically.
