It seems like we have 3 objects which are in a corrupted state.
OBJECT-2 & 3 show "Invalid attribute". It seems like the Data Definition does not support that attribute "CA.SM::IMSAdditionalPropertiesSet" OR the value is improper. My recommendation is to cross verify the Data Definition (using IdmSmObjects.xdd) with XPSExplorer. May be we'd get some hint there.
OBJECT-1 I'd check using XPSExplorer to see if all mandatory attributes are populated. If it is possible to delete and recreate, that'd be another option to pursue.
