NAV 2013 Role Center - Chart Finance Performance

My Customer is using Page 762 “Finance Performance” within his role center. He would like to add two or more pages by customizing role center. So I added
a second part of “Finance Performance 2” which he can then select. It is also possible to configure by “Select Chart” and he can see different charts. But each
time he is leaving the role center by Clicking e.g. Contacts or Customers and then coming back to the role center, the configuration is gone. My customer has
then the same charts in both “Finance Performance”. In my case the charts are disappearing at all and I have to select the charts again.

Anybody an idea?

Any help anyone?
