Did you try running the https://github.com/allegroai/trains/blob/master/examples/reporting/Allegro_Trains_logging_example.ipynb ? I just ran it twice against a Trains Server of the same version, and I can see all plots in the compare...
As for the experiment name, In some plots, the UI will display plots side-by-side, and than the experiment title will show on each plot. In other cases, each experiment will be shown as a series in the graph (perhaps this was the case in your plots?)
