Good catch. Which command did you ran?

issue related with
hf mf chk
hf mf fchk

hm, I see, the message is an indication that inside the created BIN file, the non-found keys is substituted with 0xFFF... , and not as a reference to the textual output on the screen.
[edit]
you mean that the bin-file gets zeros instead of 0xFFFF... aswell ?

To be careful
Stage 1

have generate hf-mf-7985DF4D-key.bin

This case textual message is correct
Stage 2
For the next test I delete file hf-mf-7985DF4D-key.bin from my PC
repeat with other command
[usb] pm3 --> hf mf fchk 1 d
the result on screen

have generated new file hf-mf-7985DF4D-key.bin
ALL sectors filled with 0xFF

Conclusion
chk - fills unknowns with 0xFF
fchk - fills unknowns with 0x00 and textual message 0xffffffffffff has been inserted for unknown keys. is incorrect or file is incorrect

aha, good. So fchk doesn't set 0xFFFFFFFFFFFF when it should. Good catch!
