Weird result with MSSQL 2000 mode 131

[Mem5]

Hi,
I have a MSSQL 2000 hash - mode 131 - This hash does NOT exist :
0x040016460666FF8664F8FF8F14400064F44FFF6FFF06044FF61FFF8664F8FF8F14400064F44FFF6FFF06044FF61F

When cracked, hashcat v5.1.0 displays :
0x0400164606660000000000000000000000000000000000000000FF8664F8FF8F14400064F44FFF6FFF06044FF61F:password

Not the same hash! Why does hashcat replaces the red part with zeros?

Thanks!
