Problem in Single Blog Entry Layout

Hi,

When i select Single blog entry layout then when we select blog entry then we can not select category in this box.
also this field are empty after select and single article so i can not save this menu because that field are required.

actually my problem is i have set featured blog in home page and i have called so many module in home page but i don't want those module in blog detail page but its still show those module in blog detail page.

any suggestion for that?

Thanks in advance ...
