How do I find out where I am on the map?

I just created a map, but I cannot see my player marker on it, and the tooltip says "Display Markers: No":

How do I get the markers on the map so that I can see where I am relative to the map?

Here is a screenshot of my map. Notice there isn't a player icon (which should be near the top left corner, as that is where I am):

On this image I found on the web, there's a little white circle (kind of in the bottom middle portion of the map) that shows where the player is. I can't see mine on my game.
