PT Sessions??

[swhighroller]

Hi all, hope you can help, I'm a newbie at pokertracker-have been using it for only a few days and liking it. One issue though I am multitabling on party poker-4 tables at once, but when I fininsh a Session I review my sessions stats in PT but instead of simply being one session there are multiple. Does PT count an opened table as a new session or is there a way to tell it to not count multiple table open as multiple sessions?

Cheers
