Contacts form - problems with Galaxy links

Hi, I'm the new Local Representative of ESN Lecce.

Right after the new elections for our local board, I've tried to update the Contacts Form, but I eventually encountered a problem: I've tried to create the links to our personal accounts on Galaxy to share them on the form, then I realized that some of the usernames are blue and underlined (which is the access to the link) and some others are not, so it's not possible to link the Galaxy profiles on the form.

Why is that and how can I fix it?

Thanks.
