When reimporting the hands before you deleted them, did you make sure to toggle on the Force Reimport Hands... setting? If not, it won't update the hands. This same force reimport option is required for updating all IGN grabbed hands with all known hole cards from downloaded IGN client hands, etc. It will parse every imported HH completely, instead of ignoring it completely if it detects a hand from the tournament.
I assume the tournaments were originally imported to HM3 during live play with auto import? If so it could be an auto import specific bug, or it could also be a bug in whatever build you auto or manual imported them to originally that has since been resolved in our latest build that has the new parser updates.
Can you send us the HH/TS files for those 5 tournaments?
Please zip and email the original problem hand histories and tournament summaries to us as instructed
at the bottom of this FAQ.
Make sure you also include screenshots of your reports/filters and a detailed description by tournament number, session, hole cards, filter, stat, etc. of some of the errors we need to test. We should be able to roll back to previous builds and try some forced auto import testing by dumping the files in a HH folder to see if we can reproduce the issue you are reporting.
