shot of the screen (e.g. see 0 a.d.)

When the category is unknown for whatever reason the category label is also empty thus has 0 size and causes the delegate to collapse to the top. This throws off the visual balance of the entire view. Also depending on the system font size it will cause the separator line to awkwardly stick to the [Install] button.

The category label should have a minimum size of font height to ensure the delegate doesn't collapse to the top.
