Secureline VPN activated, but ISP can still see my original IP address in the router settings. Is this normal or correct?

Yeah, its different there. But my router still sees my computer as active on the original IP address.
Your ISP can only see that you are connected to the VPN server.

Ofcourse your ISP can see your real IP.
If not, you wouldn’t be able to connect to the Internet at all.
Your ISP would not know it is you if they can’t see it and will say “He, that is not a customer of us. Lets block him.”
Looks to me you need to learn what a VPN is and how it works.
