No data is displayed when using table lat,lon coordinates

[natesales]

I'm looking to display some data using the table lat,lon format. I have some metrics stored in Prometheus like so:

pnode_status{latitude="40.657808",longitude="-74.004881",node="nyc"} 1
pnode_status{latitude="47.49312",longitude="-122.293712",node="sea"} 1
pnode_status{latitude="49.284697",longitude="-123.111935",node="yvr"} 1
pnode_status{latitude="50.09885",longitude="8.632004",node="fra"} 1

My worldmap config looks like this:

With this setup the resulting map is empty (no data is displayed)

Any help would be greatly appreciated!
