no entries?

I’m stuck. I set up TabForm5 (german version) on my iMac. It accepted 9 Forms from TabForm3 and everything functioned. The synchronization with my iPad (with IBM Claudant) looked good at the beginning. It turned out that the data in 2 of my 9 databases were blank. No entries were shown at all, although they actually should be there according to the form register (the number in the circle). When I click in the form register on one of these two forms, I get an “empty page symbol” with “Keine Eintraege“ (no entries). Nothing happens when I use the “automatic cell adjustment” command. Apart from that, I find no difference in the settings of the other forms which are displayed successfully.
Has anyone had any experience with this problem?
