I'm working on a wall map that needs to include labels for EVERY street and address range. I recognize that I will have to do a lot of editing to make it work, but I can't even get QGIS to put the labels on so I can edit them.
As you can see in the screen shot, I've chosen to show all layers, but the segments in blue, for example, aren't labelled even though they are separate lines with valid labels.
The other issue is that, of course, the map window and composer window are never quite the same.
I'm using the latest download (2.14.3).
