When using <count>> in CHECKIN/CHECKOUT/RENEWAL notices, its value is not correctly updated. A letter is prepared during the first round and then its updated with iterated data items as they come. This means that placeholders like <<count>> are not updated anymore so we can see letters saying eg. "you returned 3 items", but in the fact there is much more of them listed in: ---- <<biblio.title>> ----
We probably have the same issue with TT, updating bug description.
