Are you downloading and using the community ruleset + the registered/subscriber ruleset?  This is what typically causes this.  You have two copies of the same rule.  This is totally fine.  Snort will use the newest version of the rule by default.

So, for instance, if the community version (updated daily) is at rev:2;, and the registered version is at rev:1;.  Snort will use the rev:2; of the version, and you will receive this version.
