How to save my block code with variables?

Hello there.
I'm developing a site which can control an educational robot(by MDBT42Q).

Here's my block code that I want to save and load.

(If you can't see photo, I attached at below.)
It looks simple. First dropdown has two options(LEFT, RIGHT) and LEFT is 0, RIGHT is 1.
Second dropdown has two also, CW is 0 , CCW is 1.

It's a converted javascript code.

/* motor_move function code */
motor_move(1, 0, 0, 0, false);
//motor_move's parameters : motor_move(motor, direction, velocity, angle, wait);

If I set 'RIGHT' motor at block code and save my code, and then I load it and convert, the code shows

motor_move(0,0,0,0,false);

So the loaded block code shows 'RIGHT' motor set, but actually robot moves 'LEFT' motor.

How can I save block code with right parameters that I set before?

Help me please!
