The Brain not working as expected (or is it me?)

[Snoopy]

setup
windows 10 1903 (18362.778) , hashcat beta, new directory, no old potfile

starting server

Code:

.\hashcat.exe --brain-server

"generating my hashes and dict"

i know it is forbidden to post hashes so u have to generate it for yourself (easy enough md5)

the files are input:hash (--username option)

hash-1.txt

Code:

7:
123:
abc:
1234567890:
abcdef:

hash-2.txt

Code:

7:
123:
abc:
1234567890:
abcdef:
0:
5:
test1:
test2:
test3:

my sample dicts are also quite simple

dict-1.txt

Code:

0
1
2
3
4
5
6
7
8
9

dict-2.txt

Code:

0
1
2
3
4
5
6
7
8
9
123

dict-3.txt

Code:

0
1
2
3
4
5

7
8

123
1234567890

used client commands

Code:

.\hashcat.exe -z --brain-password=*insert autogenerated pw* --brain-client-features=3 --username -a 0 -m 0 .\hash-1.txt .\dict-1.txt
.\hashcat.exe -z --brain-password=** --brain-client-features=3 --username -a 0 -m 0 .\hash-1.txt .\dict-2.txt
.\hashcat.exe -z --brain-password=** --brain-client-features=3 --username -a 0 -m 0 .\hash-2.txt .\dict-3.txt

the potfile starts empty and after each run 1 pw is found/added (7, 123, 1234567890)
