bruteforce sha1 with hashcat

[aprivate]

hello everybody!
i have a pretty simple 20 lenght hash to bruteforce
with SHA1 algo and 8 numbers length, salt has to be 0000000000000000

=============== hashcat log======================
hashcat-cli32.exe --hash-mode 101 --attack-mode 3 --salt-file C:/hashcat-gui-0.5.0/hashcat-gui-0.5.0/salt.log --bf-cs-buf 1234567890 --bf-pw-min 8 --bf-pw-max 8 C:/hashcat-gui-0.5.0/hashcat-gui-0.5.0/h.txt

Added external salts from file C:/hashcat-gui-0.5.0/hashcat-gui-0.5.0/salt.log:

=====================================================

both programs ighashgpu and hashcat are finishing the bruteforce
for the same input options process in couple of seconds,
but ighash found the password and hashcat does not
why hashcat cant find the password?
maybe i missed some options?
thank you!
