Unable to set A4 and A5 as output



Using mBlock, I can set A0 to A3 as output using the set digital pin 14 (15, 16, 17) output as HIGH (or LOW) block. However, I can’t set A4 and A5 as output using the same block.

I tried to upload the program to Arduino (using the Arduino Program block), and A4 and A5 works as output.

Is this a bug or did I miss something?
