Hi VirtuousFish83 , are you using your own installed Trains Server?

And an example of the missing comparison:
the two experiments 2. plot on the first one 3. plot on the second 4. comparison plot only shows other plots (only the confusion matrices)

And what is the Trains Server version?

0.16.1-320

With matplotlib I only get the suptitle

And the comparison for the confusion matrices without the name of the experiments

Experiment names marked in red

Yes

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?)

VirtuousFish83 see below what I see when I run the example twice and compare:
