Hashcat office collision attack (9810 and 9820) doesn't work

[Fabius71]

sounds similar to this problem https://github.com/hashcat/hashcat/issues/2067

I tried with the demo file provideded in this thread and it indeed work and hashcat found collided passwords.
But when i try with $3 files it gives me wrongly collided passwords.

I followed this tutorial but nothing changed.
