Digests different from unique digests

[Alessia97]

Hello everyone, I’m trying to crack in brute force way a file of ntlm hashes. The problem is when I start hashcat it writes two different numbers of unique digests and digests . Bu there are no duplicates in the hashes file. So, maybe , is a memory problem? I have to chunk in different files my hashes file ?

could it be, that in your file the empty ntlm hash is included? or how big is the diff in both numbers?

This is the output:

Hashes: 847223402 digests; 268435456 unique digests

I've cheked and there are not empty lines
