Contact Alpha tabs

I just upgraded one of my users from 7.0.3 to 8.5 Notes Client. When he goes into his Contacts his alpha tabs are grouped. So instead of having a tab for each letter of the allphabet he has one for A - D, E - I, etc. I cannot figure out why his is like this. Is there a setting I can change to get the full alphabet tabs back?

Subject: The Grouping of Alpha Tabs is based on Real Estate

His alpha tabs are being grouped because of the (vertical) size of his client.
