Biography and Skills for a new Expert

My website has:
- 100% Translated in Romanian Jobs & Experts plugin
- TwentyTwelve theme

In the website there are the following users: admin, me, a coleague of mine. Me and my coleague have Editor roles.

I managed to create an Expert profile. I don't know to whom the Expert profile is attached: to admin or to me? I couldn't find in database where the expert profiles are stored and I don't know if a wordpress user can have several Expert profiles. If Yes, it is good to have several Expert profiles? For what reason?

I try to create another Expert profile and I cannot create it. My coleague cannot create her Expert profile. REASON? No Biography and Skills textarea present. I attach the screen captures.

Help me, please!
