Motor right&left backward wrong code

[enkith]

I used the blocks for 'motor DC'. When I put the 'spin motor DC' on 'right&left' 'backward' it generates C-code that doesn't work.
Instead of

digitalWrite(l298n_in3,HIGH);
digitalWrite(l298n_in4,HIGH);
analogWrite(l298n_enb,(255));

it should be

digitalWrite(l298n_in3,HIGH);
digitalWrite(l298n_in4,LOW);
analogWrite(l298n_enb,(255));

This doesn't create an error message. But the motor won't spin, because the state 'HIGH, HIGH' is the same as 'LOW, LOW' - stop.
I'm attaching a screenshot.
