Incomplete List Scroller on iOS

I'm having an issue with my lists on iOS (both device and simulator).

The scroller always seems to be truncated or incomplete. I've done some googling around but couldn't find anything related.

I recently started my project from scratch as it used a previous version of Sencha Touch but now it's using 2.4.1 and the issue persists.

I'm not sure if this is a bug so I thought I'd post here.

Here's a pic of how it looks:

Notice how the scroller actually ends at the bottom of the view, but there's a gap in the middle of it.

Anyone has any idea of what's going on?

If it's of any use my app is using Cordova too.
