GPS trackers from TTN are not displayed

Hello, I am a newbie in Node Red and Tago.IO
We want to create a dashboard. This worked very well with the temperature sensors. Unfortunately not with the GPS trackers. I cannot select the variable. In the Life Inspector you can see the data from the sensor, including a locations field and the correct coordinates. What do I have to change to make a pin appear on the map?  I'm attaching a screenshot. Thank you
