tellico shows only the half information in the entry view

Hi,

After a succesfull data migration of my DVD and my CD DB, yesterday all 
works fine.
Today it shosw only the half of the data in the entry view.

Album:    General, tracks , cover
Compact:    all
Default:    General, cover
Fancy:   only the title
Fancy2: only the title (downloaded yesterday in the evening, and used it 
as my template)
Video: General and cast, cover

All data are still in the file, if I look in the entry editor.

Any ideas are welcome!!!

Michael
