Seo urls are tracked, rest not!

I am a piwik newbee and i am settingup a piwik for a client.
I am integrating to a cs-cart. All product pages have seo friendly urls like https://troumpoukis.gr/seven-1356106-blue.html
and are tracked correctly. Cart and Order complete pages are like
https://troumpoukis.gr/index.php?dispatch=checkout.cart
and they are not tracked at all.
Tracking code is in all pages.

Any ideas?
Thanks
Panos
