Express Renewal - Different number of PC Protection shown when currency is switched

My NIS 2011 license has just expired and I am interested to renew the subscription online. When I click on the express renewal link, it brought me to the US site where it shows me that the product protects up to 3 PC. However, when I change the country to Singapore to view the S$, it shows that the product only protects 1 P.C. When I first purchase the NIS 2011 from the retail (in Singapore), it shows that it is entitled to protect up to 3 PCs. Please kindly explain this difference ASAP as I urgently need to purchase and activate my license.

 

By the way, I have chatted with Live Agent on this. Both the Agent and his supervisor are unable to give an explanation for this problem.

 

Thanks for your help & support.
