You're probably encountering a current bug in how we generate gravity.list. Your IPv6 address in `/etc/pihole/setupVars.conf` includes the `/64` at the end, which we are not accounting for when generating gravity. This leads to invalid entries, which are ignored, effectively removing any IPv6 blocking. Remove the `/64` from the end of your IPv6 address in `setupVars.conf` and run `pihole -g`. This will be fixed in the next release.
