[Koha] Upgraded to 16.05 and can't retrieve Patrons by Surname

Hi, I upgraded to 16.05 from 3.18 this evening. After the upgrade, which seemed to work very well, I find that I can't lookup Patrons using either the Search facility searching on Surname, or clicking on one of the Alpha buttons (the retrieve all Patrons that start with "S" for example). I notice that there was an issue recorded already (ticket 14193) for this problem, which should have a fix included in the 16.05 release according to the documentation. Am I missing something here or should I roll back to the backup that I took prior to starting the upgrade? Regards, Tim Auld Northern Philatelic Library Minnesota. Ps. I apologize if this question has already been asked and I missed it.
