Problem with posts layout and header

Hi. I'm using spirit and upfront.

I use category items in menu to display category posts. Header is displaying "blog". I changed that for "realisations". For another category, I have to change this header. I've edited it using upfront. When saving, a message ask "do you want to save for this post or all similar posts." I choose "this post" but header is changing for all categories.

I've tried inserting posts direct with upfront but the layout is not the same than when I use category pages in the menu and I prefer this layout.

What should I do?

Thanks
