Duplicated mask

[NewChapter]

Obviously it means hashcat does not recognizes your line endings.
Perhaps use a editor like Notepad++ or any other capable editor, enable "show line endings" to see what line endings you are using in your mask file:
* CR LF (Carriage Return + Line Feed, used in Windows), editor will show '\r\n' at the end of your lines
* LF (Line Feed, used in Unix and Linux), editor will show '\n' at the end of your lines
* CR (Carriage Return, historically used in older Mac systems) editor will show '\r' at the end of your lines

Now try replacing the line ending to any other type and I would very much expect this to fix your issue. Although I do not know the cause, probably you generated a mask file with a different line ending than hashcat is expecting.

I created the masks in Notepad++.
I took the files from the “masks” folder and copied them.

I checked the file just now, and there is “CR LF” at the end of each line.

I have an idea. Perhaps the problem is in the set of parameters. If they are repeated and there are more than 7 in one mask, for some reason it combines them.
