'About' metrics description not shown on Benchmarks page

[Nicolás Palopoli]

On the Benchmarking page, when the cross-validation benchmark is selected, a drop-down menu allow to choose whether to display the Complete benchmarking set or an individual class dataset.

When the Complete benchmarking set is selected, the “About” section at the very end provides information on the chosen metrics such as AUC, Recall, etc. However, this section is not shown when an indivudual motif class benchmark is selected instead. This should be be fixed so that this reference is always shown.
