The reason was Understanably an operator wanting to use a Freighter....especially an -PF or -PCF over an -SF but why spend to convert a B752 to a B752PCC......
Here is your answer:
The 757 combi is designed to replace the DC-8-62 combi, since it can do essentially the exact same job but is much more modern and fuel efficient.
The market for combi operations is very limited, but there are other 757 combis being used for NATO and military purposes - very different missions from the PCF/PF/SF missions - plus a single one at Royal Nepal that was a factory product and not a conversion and is unrelated to these later developments.
