Website exception list question?

I’ve noticed that when I paste a website in the exception list & click add it shows it on the as a domain list as just the domain name, but if I copy the domain name & paste it into a browser, it is the whole original site link entered.

So my first question is does Privdog ignore everything but the domain name it shows on the list or does it only allow the exact site information originally entered?

My second question is why when I enter the exact same site link into Privdog Dragon that Privdog Ice Dragon accepts, why does Privdog Dragon say Wrong domain?

Third question why does Privdog say Wrong domain when it adds the domain to the list anyway (on occasion)?
