#9 question regarding -t feature

[hdaf]

this is the command
crunch 4 4 -f /home/hdaf/crunch-3.4/charset.lst hex-upper -t ,aa% -o /home/hdaf/crunch-3.4/test.txt

the hex-upper charset is hex-upper =[ABCDEF0123456789] and i am expecting something like
Aaa1
Aaa2
....
Baa1
....
Caa1
....
Daa1
....
Eaa1
....
Faa1
....

but i am getting

Aaa1
....
Baa1
....
Caa1
....
Daa1
....
Eaa1
....
Faa1
....
Gaa1
....
Haa1
....
Iaa1
....
Jaa1
....
Why the programm is using all the uppercase letters instead of ABCDEF from the char set i specified?
Is there any way to use only the letters i want on the -t pattern?
Thanks in advance!

I think you want

crunch 4 4 -f /home/hdaf/crunch-3.4/charset.lst hex-upper -t @aa% -o /home/hdaf/crunch-3.4/test.txt
