the count is supposed to continue from where it ended at the time of checkpoint, but instead it is starting again from 0

Yes, we know. Docker is broken. Also see #1223 and #1243.

You can always use Podman as a drop in replacement if you need checkpoint/restore support.

Closing this as this is a docker problem and not CRIU.
