Format: Option bug with Custom Post Types

Hey,

I’m having a problem getting the Format: Option setting working with custom post types. Right now I’m using the Format: HTML setting, which is working fine with showing my custom posts in the widget grouped by Monthly. However, I’d like to change that to Format: Option so I have a pulldown instead of a list of text links in the widget. But when I select the Format: Option setting and save it, the pull down appears, but it is only showing normal blog posts as choices, not the custom post types. Anyone have any ideas on this? Thanks in advance.
