Exported PNG does not include Node labels - checkbox is clicked

[broorg]

Everytime I try to export my graph as a PNG file it contains no labels.
The "Show Labels" box is checked and in the Overview everything works fine but the PNG does not include any text.

I also don't find the option to set the wanted parameter for the label?

This might be because your label column is empty. Try copying the data that you would like to use for your labels into this column and see if that works?
