how can some later additions appear on their respective pages before earlier ones
This sounds like an error.
I´ve had some problems some time ago already because of the fact that there are too many connections too handle. When generating the individual site pages, the query often times out. And as a result of that half of the connection pages have not been updated.
The main Connection page with the latest added connection does not have the same problem, because it shows the updates real-time.
What I could do to resolve it is to make the individual connection pages Dynamic too. So I cannot longer forget to update them and the time out-problem does not exist anymore.
