"Default front page" for virtual sites not working

With two urls domaina.com and domainb.com, domainb.com is set with Conditions and Virtual Sites to use different site information.
The condition is working, and the site name and slogan are being set properly, but for some reason the "default front page" is not.

domaina.com is set to use node/1 as its default, while domainb.com is set to use node/2 , but when you visit domainb.com it is still showing node/1 (even though the site name is set correctly).

Probably something is set wrong but it's not clear to me what...

Thanks
