it seems you have duplicated rows in the CMS_UIElement table. You can check it running following script:
COUNT([ElementDisplayName]) AS NumOccurrences
GROUP BY [ElementResourceID], elementname
HAVING ( COUNT(elementname) > 1 )
Could you please send me the rows which are duplicated, then I can tell you which one should not be there.
As for the second issue. Online Marketing

in the Site Manager - Settings - System - User interface section. Please make sure that Site: global is selected in the upper-left corner.
