Menu settings bug. The following settings work incorrectly: "Change of the folded side", "Copy of the folded side"

Menu setting bug in the Personal Account. The following settings work incorrectly: "Change of the folded side", "Copy of the folded side" I specially created the pages on which I set up the menu, since different groups of users need a different menu, I decided to create pages and use the menu on them as a "Template" and then use the "Change to customize the side" setting. So I set up the page and the menu on it. Then I went to another page and in the settings "Change the settings of the side" I select the page on which the menu is configured. [file]17721[/file] But after saving in the page menu settings, the last page from the list flies and is shown. [file]17722[/file] But even the menu of this page is still not applied, the standard one is shown. And the setting "Copy the new side" does not work at all, after saving the menu is not copied. Please fix the problem
