Hello Valentijn,
::/0 does not describe no IPv4 address, but all IP addresses. So when
you write ::/0, all IPv4 addresses are routed through the tunnel. If
you don't want IPv4 routes, you can simply omit them in AllowedIPs (so
only put IPv6 addresses there, or only address which should go through
the tunnel).
Greetings
