Tracking.... weird


I am quite a newbie. I found something weird and I have no idea on how to solve it
I’ve installed a webserver and another machine with Piwik. They are on the same LAN.
I’ve got 2 different Web

Each of them have been declared separately

If I log on the Piwik page for the web “aa”, I can found let’s 10 lines related to aa AND 1 line relateed to a page from BB ???
How could it be ?
Why a tracking link of the BB web is on AA log ???

Thanks and regards,

I think that I effectively found a difference between 2 script…

_paq.push(['setSiteId', **6]**);

Sorry, I should do this checking before :frowning:
