Unfortunately there are subscriptions that refer to old distroseries, so they can't be just deleted without losing DB consistency.
Two options for fixing this bug would be:
- Migrate old subscriptions over to some newer, supported, distroseries, then delete old distroseries. Or,
- Add a 'obsolete' flag to DistroSeries, and don't display those in the review dropdown.
Both these solutions should be a day's work, maybe a bit more.
