7z hash not recognised

[Snoopy]

regarding your screenshots or posted outputs your hash starts with

Code:

$7z1$

(initial post) or 

Code:

$7$

(given output)

but it should be

Code:

$7z$

hashcat just tells, that your input hash is malformed

It seems I made a mistake in the first post. The Hash starts like this:
$7z$1$18$0$16$00000000000000000000000000000000$...

I am completely stumped. If the encryption is malformed by cobian, why does winrar have no issues in decrypting the password? What knowledge am I lacking here?
