Page Title shows "Untitled" in

Hi there,

My page runs on the following system:
- Wordpress 3.6.1
- Theme: Magazino (http://wpthemes.co.nz/magazino/)
- MarketPress ecommerce plugin (current release)

On the automatically generatet pages, the title on the page shows "Untitled". It looks like it's not taken over to the page from the plugin.

You can see it here:
Base page is OK: http://int.stadtrat-zuerich.ch/spenden/
Automatically generated page is not ok: http://int.stadtrat-zuerich.ch/spenden/produkte/

Do you have any tipps how this can be fixed?

Thanks in advance,
chris
