I am a new user.

When entering both Leads and Contacts, after Saving, my user name is superimposed in the Lead and Contact name afreas. Except that when I clcik on a Lead or Contact for detail, the correct name appears at the top of the panel.

See attached creen grab for example

What am i doing wrong?

Thanks,
