The labels of the datasets used in the experiment page (user micro-site) are not consistent with what is actually used on the related experiment. For example, check your user micro-site (on the production platform), for the public experiment: /tutorial/tutorial/full_lbphs/1/atnt-lbphs/, the displayed dataset on the user micro-site is "banca.Md", where this experiment clearly uses "atnt.idiap". If you click on it, the experiment display page shows the right configuration.

This must be an issue with the javascript parsing on the experiment list page.
