syncing of Journler database via iDisk

I am using iDisk to sync my Journler database between various computers.
The Journler database is synced correctly from my local iDisk to the remote iDisk on .mac, except all "_Text.jrtfd" directories and the "Entry.rtfd" files therin which are not kept up to date after the initial sync anymore (i.e. they are initially uploaded to .mac, but never synced anymore afterwards).

All other content of my iDisk seems to sync correctly.

I am using manual syncing of my iDisk, i.e. the sequence is always
1 switch on computer
2 sync iDisk
3 open Journler, update whatever entries, close Journler
4 sync iDisk
5 switch off computer

Any advice what I can do to remedy the situation??
