Content encrypted files have encryption, but only using the generic MOBI key (not a PID-specific key). This means that can be read by any MobiPocket Reader software, on any device, but not by any non-MobiPocket software. There is a version of mobidedrm.py that strips content encryption, see
Mobipocket Decoder Tool #176.
If you want Calibre to format shift your MOBI files they must be DRM-free. The python script mobidedrm does this, but note that it is thought to be illegal to strip DRM from ebooks in many countries.
Calibre should be able to catalog DRMed MOBIs, including the metadata (since this is not encrypted). So it may still be worth submitting a Calibre ticket for one of your content encrypted ebooks.
