Variable _v_colour_temp is created two times when there are two RGB-LEDs configured

[el-voss]

Describe the bug
I have two RGB-LEDs at an Arduino UNO and configured them in the Open Roberta Lab. When I open the code view after that, there are two variables with the same name _v_colour_temp. And when I add some blocks, that use the RGB LEDs, this variable is not used at all:

// This file is automatically generated by the Open Roberta Lab.

#include <Arduino.h>

#include <NEPODefs.h>


int _led_red_R2 = 4;
int _led_green_R2 = 5;
int _led_blue_R2 = 6;
int _v_colour_temp;  // first occurence because of first configured RGB LED
int _led_red_R = 1;
int _led_green_R = 2;
int _led_blue_R = 3;
int _v_colour_temp;  // second occurence because of second configured RGB LED
int _led_L = LED_BUILTIN;
void setup()
{
    pinMode(_led_red_R2, OUTPUT);
    pinMode(_led_green_R2, OUTPUT);
    pinMode(_led_blue_R2, OUTPUT);
    pinMode(_led_red_R, OUTPUT);
    pinMode(_led_green_R, OUTPUT);
    pinMode(_led_blue_R, OUTPUT);
    pinMode(_led_L, OUTPUT);
}

void loop()
{
    analogWrite(_led_red_R, 204);
    analogWrite(_led_green_R, 0);
    analogWrite(_led_blue_R, 0);

    analogWrite(_led_red_R2, 51);
    analogWrite(_led_green_R2, 204);
    analogWrite(_led_blue_R2, 0);

    analogWrite(_led_red_R, 0);
    analogWrite(_led_green_R, 0);
    analogWrite(_led_blue_R, 0);

}

Expected behavior
When the variable _v_colour_temp is declared, it should have added the name of the RGB-LED - like
int _v_colour_temp_R;
int _v_colour_temp_R2;

Alternatively, the variable shouldn't be declared at all, if it is never used (which I am not sure).
