As you obviously do not know what a FDR looks like or is comprised of, let me educate you.
There is a chassis, a CSMU and a ULB. The CSMU is mounted on the chassis and the ULB on the CSMU. Each has it's own part and serial number.
The entire assembly is called FDR.
BEA shows the recovered part of the FDR, which is the CSMU. They also list the FDR from which it came by maker, model, part and serial number.
It is only in your biased layman's mind that there are any inconsistencies.
