This will require changes in Laniakea, which is currently stuck in a PostgreSQL transition. It has been on my todo list already though to revise the synchronization process.
The likeliest chance is that these issues are from an older, broken sync (the more annoying option would be that this is an issue that still exists).
In any case, it's quite high up on the task list (I was aware of the general issue so far, but didn't know that it affected so many packages).
