VPN works fine with IPV4 but IPV6 is still my original one

[Paddy]

Hi!
I'm new to this site. I'm Patrick.
Set up my UT phone pixel 3a yesterday and set up an old NordVPN account manually. Works fine BUT if I check the IP the V4 is in that state I choose and the V6 is my original. I didn't find a solution so far. Also tried to enable IPV6 with Terminal sudo nano but it says it's a read only system.
Has anyone an idea?

Some info for my VPN setting:

Using VPN editor

Remote is the correct server [...] .30:1194
Type is password
CA certificate downloaded by NordVPN

Advanced
Use gate 1194
Use LZO (a must with UT and NordVPN)
use custom VDT: TUN
Use MTU 1500

security
Cipher aes 256 cbc
With HMAC sha 512

Tls
Use additional Tls (uploaded key correct from server list)
Key direction 1

That's it.

Looking forward for some ideas.
Thanks a lot

I have exactly the same after a setup with ProtonVPN. Is there a solution to unset the IPV6 address or also get a address via the VPN provider?
