Do you block some menu items for user role with “Admin menu access” add-on?
If you ‘yes’ and you use ‘block not selected’ model then URE blocks and redirects to the 1st available menu item (dashboard) any links, which are have the same base as the menu items, but have additional arguments/parameters in URL.
2 workarounds are possible:
1) Use “Block selected” model in “Admin menu” settings for this role;
2) go to the “Settings->User Role Editor->Additional modules” tab and click “URL parameters white list” link. Find the menu item and add for it additional URL arguments which you allow for this menu item.
