Old logs not being processed

Hello, I have a situation where the log files for a specific bucket were enabled and running for say a month, however when I went to check on them in S3 Stat the bucket wasn't listed as being processed and charted. So I added the bucket to the list and waited 24 hours. Now the graph shows up but it is only showing results from the point I enabled it in S3 Stat on... So I went and checked the log folder and made sure everything was pointing to the right place and while I was in there verified that there were really old logs going back over a month.

So my question is why wont S3 Pull the data from the old logs and is there a way to reset of force it to go and reread everything that is in the log folder?

Thanks,
Andy
