This problem is resolved on all newly deployed instances. On pre-Jakarta instances, go to sys_properties_list.do and check the value of the glide.sc.reset_cascade system property. If it is still false, set it to true to force a variable cascade when navigating back and forth in the order guide. Since late Istanbul and Jakarta, this property is set to true out-of-the-box.
