I have delegated a Decision table. My application has customized portal in which i have added navigation named Configuration in our customized portal. In Configuration tab i am getting the Delegated rule as well as Edit Button. But on Click on Edit Button rule is not opening the rule for me though i open through Manager portal , instead i am getting  a popup message . I have shared below Screenshot for reference. When i analysed i could see "pxIsPortalSingleDocument" when rule is not failing. It should fail to get the correct Edit button that opens the rule.
