Hi,
it seems you have duplicated rows in the CMS_UIElement table. You can check it running following script:
SELECT elementname,
COUNT([ElementDisplayName]) AS NumOccurrences
FROM [Ivanat_6].[dbo].[CMS_UIElement]
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 features are not available for ultimate edition. They are supported with the higher EMS license. If you do not want to see these UI elements you can check option
Hide unavailable user interface in the Site Manager - Settings - System - User interface section. Please make sure that Site: global is selected in the upper-left corner.
Best regards,
