Registration New Household

Dear all:
HEWs reported being unable to register a new household after selecting a village name to pass on to the next page. It needs them to wait 4 - 10 minutes on a few tablets with the user version 7615 but tablets with version 7448 are not an issue as I tested it. Please see the details and devise a solution as the HEWs have begun to complain about their time efficiency.

Best regards
