When my homebrewed style for road symbology and labeling is saved to a qml file, I am unable to load the labeling information from the qml file onto the same shapefile. This is the case for both the same map document and a new map document. The saved style loads but the labeling is blank. Here is a tar.gz with the roads shapefile, qml layer, and interstate symbol. Is this a bug or am I doing something wrong?
