STEPS TO REPRODUCE
1. Select a contact to update
2. make all changes necessary 
3. Click save or ok

OBSERVED RESULT

When you commit those changes to the contact, they seem to show up in the summary of that contact for about 2 or 3 seconds and then disappears.  when you go to check to see if those changes have taken effect, some of them are there but not showing in summary, and the rest have not been committed

EXPECTED RESULT

Go into the contacts module make the needed changes and save those changes and have those changes retained.
