No, it doesn't. Dmidecode will display the "Manufacturer", "Product
Name", "Version" and "Serial Number" fields of this structure, whether
they are defined or not. The only thing that would make dmidecode not
display these fields is if the overall structure length is less than
the minimum allowed in the SMBIOS specification (8). I suspect that
this is what is happening in your case.

No, I've never seen this. All systems in my test suite have size 8 for
this structure.

Please provide the output of:
dmidecode -t 2
dmidecode -u -t 2
