Also, in Arduino-speak, "sketch" means code, not a schematic.

sorry for that.

You'r right PaulRB. i had changed the code also as you can see below. but the problem is persist.

    byte Data = B00000000;
    

    bitWrite(Data, row, 1);
    bitWrite(Data, column+4, 1);
    digitalWrite(latchPin, LOW);
   
    shiftOut(dataPin, clockPin, MSBFIRST, Data);
    
    digitalWrite(latchPin, HIGH);
