strange output statsprocessor

hey all,
i wanted to check the kind of passwords oclhashcat would be checking when i do a bruteforce for a 10 digit hex password so i put this in statsprocessor and got some strange output after the first 15 lines:

statsprocessor-master/src/sp64.bin --custom-charset1=?dabcdef --hex-charset --pw-min=10 infinitum10digithex2.hcstat | head -n 20

... (i cut the first lines to make the post shorter)
3531ea4226
3531
3531!
3531"
3531#
3531$

i have tried with 2 different hcstat files generated from 2 different 10 digit hex dictionaries one of which i hand made, and i have tried with only --hex-charset and only --costum-charset1=?dabcdef and as you see above with both. all the same.

if anyone here can see if i do something wrong please let me know.

thanks.
