Problems getting in to Showcase module

Hi there

I am having an issue getting in to the showcase module.

Please see this video, it is the same on all of the showcase modules.

The reason I went looking to get in was on the home page only 10 posts are shown in the showcase module.

Is this standard or can it be changed?

In the module shown I know how to change it, (if I can get in) but I am talking about the showcase module on the main blog page.

Please let me know what I need to do to fix it.

Many thanks
