CD#5 missing Kibri & Vollmer files??

[BenPerr]

Hello,
I am on V16 and I bought the additional CDs for scenery in Sept. 2023.
On the CD#5, I am looking for the Ki39010 Falkenstein Castle to put on my layout but I cannot find it, even though it is in the PDF catalog.
Upon checking the website 3D models for what other models are on the CD#5, it seems that all the Kibri and Vollmer are missing, but the Faller, Piko, Auhagen and others are there.
Looks like all my Kibri files are coming from other CDs (like #12 is OK)
Is there something weird/known about this??
Thanks for your help.

Forget the above, I finally found the Ki39010 Falkenstein castle, but under Ki9010 (without the '3').
Looks like some mis-labeling.

Hi BenPerr,

Kibri has changed the numbers from four to five digits. It depends on the age of the kit, which type of number you must search for. Some (many) of the old four digit numbers have been changed to five digit numbers.
Wintrack uses the four digit number, if the kit was released before the numeration has been changed.
