ou still have those duplicate ID’s they are not really acceptable in fact they may well cause issues as ID’s must be unique to a page – it’s not a flexible rule.
Look at those two pages ‘group directory index’ and ‘single group display’ you are missing a fundamental class that gets added to the body tag ‘.right_sidebar’ without that class present your sidebar does not have the required ruleset applied.
You will need to work out how your theme ‘framework’? applies that class for a given view and ensure it’s applied in respect of your groups single view pages (and any others )
