Can you explain this

can anyone explain why this happens sometimes when i do mask of necalli its half circle k but then other times its half circle p (i tried to post pics of it but for some reason i cant figure out how)

Do you have a pic of your gamepad and/or stick? If you are sure it is not user error, I suggest opening it up and using and air-can to blow out any gunk/dust.

i took pics of the command list twice during the same match when it changed

i took pics when it changed mid match but i cant figure out for the life of me how to post pics on this site
