I am getting closer. I saved tages from library in version 10, then I updated the library in version 11. I now remember what started this. I removed all keywords and these albums where the only ones that had them. and only on a couple of songs not on the full album. The full albums were set to null.
version 11 (in tag mode the duration and bitrate ar ok) but not in file type info.
