if you count/sum only the A B C D ... it is normal to get

FILE_NAME A B C D

CHECK 2 3 2 1

JAPAN A is in FILE_A and FILE_B so 2 times

CHINA B is in FILE_A (twice) and FILE_B so 3 times

MALY C is in FILE_A and FILE_B so 2 times

if you don't want to count/sum after the first time, tou have to test the exists before.
