single portfolio page format issues

Very frustrating, but the portfolios on my site look like crap. For some reason, the “add portfolio” page in the dashboard gives me no options for “sidebar” location. It’s just blank when I try to click dropdown. Since the default blog template forces a right sidebar, the single portfolio items have a blank space and over ride the “sidebar text” of the portfolio item. How can this be fixed?

Thanks for your time.
