Hello All,
From add menu item ,  i select Content Category (blog view) but i can not select multiple categoriess?? when u select one it works but when you select multiple it turns    index.php?option=com_content&task=blogcategory&id=0&Itemid=75
Is there anyone had this problem?? or knows the issue?

You can create a link menu to the section of categories you want show as blog list.
