NORD VPN "kill switch", I can't de-activate

In the first few days, I could disconnect it anytime anywhere and still have internet access. That the way it should be. My problem began after I activated the NORD VPN setting called "kill switch". Now if the VPN becomes disconnect, I don't have internet access. That's what it is supposed to do. So now if I de-activated this "kill switch", I still do not have internet access. This should not happen. This is only true when at home using my wifi router. When at work, I have internet even if my VPN is disconnected. Also my work uses the same wifi router as i do at home...not that this matters but saying as it might eliminate the router as the problem. So weird. It like the NORD VPN "kill switch" is permanent only on my home router (this is where I was when i first activated the "kill switch" feature. Any ideas out there of how to fix this?
