DES weird result

[Mem5]

Hi,
According to https://hashcat.net/wiki/doku.php?id=example_hashes , DES sample hash is "hashcat1".
But I find  "hashcau0"
Why?
Thanks!

Code:

hashcat.exe -m 14000 -w 4 -a 3 a28bc61d44bb815c:1172075784504605 hashca?a?a
hashcat (v6.1.1) starting...

Edit:
Second run, second password found: hashcat1
Third run , third password: hashcau1

Collision on the last two?

Because of the way DES works, only some bits have to match to get a match.
