You seem to be misunderstanding what "You have 2 logs according to Project-GC" means. An announcement is a log, a note is a log, a DNF is a log. Having multiple logs on caches is normal, expected and does not have any general effect on your total amount of caches.
If you've updated an attended log to a write note log there might be a delay in the system before that's caught, but the script has nothing to do with that. If you're still seeing the issue my advice would be to use the self support-button to refresh your cache finds or the specific cache.
