Not sure what to tell you as it works fine for me on a clean Zen Cart install ...
You can check two other things ...
1 check the files:
/includes/configure.php
/admin/includes/configure.php
do they both use the same database?
2 go to phpMyAdmin for your database and browse the configuration table for the configuration_key for:
PRODUCT_INFO_PREVIOUS_NEXT
and make sure that you only have 1 configuration_key for that value ...
