No visible objects in the map

[Tqnsls]

Hi Carsten,
I just installed the module in our test environment but unfortunately there are no hosts showing up.
As you can see in the screenshot, we have several hosts with configured custom-var geolocation, which we are using (and it's working) in nbuchwitz 's map module.

Could you please have a look at this?

Thanks, @Mikesch-mp

Custom-Vars in Use

nbuchwitz's module shows hosts, yours doesn't
