When a model is loaded, its styling is included with the file. So let's say someone saved a file last week, and that we changed the size of start/end signals yesterday. If that someone loads his model today, he will still get the big start/end signals (instead of the small start/end signal included with the editor). This can be solved by either using a format that doesn't include formatting (which we'll have to make ourselves -.-') or do a pass over every loaded graph to make sure it is styled correctly. The second option is probably the appropriate one, since we already have a good format for saving models now.
(Or we could only make visual changes every major editor release, and mark the save files from different releases as "incompatible". Brr.)
This is not a bug, but a feature: any visual customization is carried over on save/load, and the user can manually change the style of any model via the dedicated option, which is enhancement #14
