Try the following steps to resolve the issue:

  1. Search for table entries for titles and suffixes in Configuration that could contain the last name or first letter of first name and remove them
  2. Search for Hunt,J (with no space) in Quick Find and this will open the constituent
  3. Use 'Open a constituent' instead of Quick Find, this will also open a constituent record
  4. Check the Alias as well - data in the Alias field may keep the same constituent record opening each time
