vBulletin < v3.8.5 salt length issue

I'm trying to crack an old vBulletin (2611) hash, with a salt length of 5 characters (usually they are 3 characters but this one is 5), and hashcat doesn't like it " Token length exception"

I know other people have been able to crack these with a 5 character salt length, what am I doing wrong?

Thanks
