I want to see the members signed up in Lyon, which is in the Rhône-Alpes region in France.
So, I click on France which opens up the list of regions. Rhône-Alpes is at the bottom of the list, which is in two columns, the second one a line longer than the first. That last line is unclickable - all the others work fine.
The same thing happens if I click on Normandie - I get the towns; the last one is Yvetot, again unclickable.
