Delete abnormal network connection

[kadausser]

I have recently installed Lubuntu 21.4 on my (Dell) computer. Later I tried to install Proton vpn too, but the connection didn't work. I saw that on the desktop (bottom right), next to the Ethernet1 network connection, there was also the connection of the vpn + another connection called pvpn-ipv6leak-protection. I uninstalled the vpn, but this second link remained and is active when I turn on the computer. I cannot delete it as it is not present in the Network Manager. The system displays 'Ethernet1' pvpn-ipv6leak-protection. How can I delete this second string?
