There is nothing mysterious or even unusual about absence of material “missing” from the files as they are posted on the internet.
In the main they are still there, just they were treated with due confidentiality. Particularly those withheld at the behest of the British police, as can be seen from the second cite below.
The following may be of relevence to the discussion of whether or not CB’s name was passed from the PJ to SY.

INFORMATION
Concerning the information in Folios 293-300, I can inform you that in spite having carefully explored and analysed with minute detail, nothing useful was found of interest to the investigation. In spite of the individuals mentioned having criminal pasts linked to illegal practices of a sexual nature, no relation was detected with the disappearance of the British child, Madeleine McCann.
