I just noticed an issue with the AppDB while I was browsing. The data from the latest submission is shown by default, but it doesn't appear in the table of testing data (the block below which says what OS, version, ratings, etc). So it means you're unable to edit the latest submitted test data for each app in the AppDB or see what rating, version of Wine and submitter it has.
Wasn't sure where to send this so I thought I'd throw it into here as it's likely to find the person that needs to correct it one way or another.
