I cant use all of my pwm pins only 8 of them

Hi im new to all of this and im trying to use servo motor with PWM, so my problem is this out of 16 PWM Pins only 8 of them is working 0-7, 8-15 isnt. i read online PWM is divided to 2 groups. so do I need to do somthing extra to use the 2 groups? maybe somthing i dont know about im adding a picutre of the setup of my code

 #define Servo_0 13
    #define Servo_1 12
    #define Servo_2 14
    #define Servo_3 27
    #define Servo_4 26
    #define Servo_5 25
    #define Servo_6 33
    #define Servo_7 15
#define Servo_8 2
#define Servo_9 4


#define PWM_Channel0 0
#define PWM_Channel1 1
#define PWM_Channel2 2
#define PWM_Channel3 3
#define PWM_Channel4 4
#define PWM_Channel5 5
#define PWM_Channel6 6
#define PWM_Channel7 7
#define PWM_Channel8 8
#define PWM_Channel9 9

#define PWM_Resolution 8
#define PWM_Freq  50

String str;


void setup()

 ledcSetup(PWM_Channel0, PWM_Freq, PWM_Resolution);
 ledcSetup(PWM_Channel1, PWM_Freq, PWM_Resolution);

{
  int box1 = map(angle1, 0, 180, 10, 35);
  int box2 = map(angle2, 0, 180, 10, 35);
  ledcWrite(PWM_Channel8,box1);
  ledcWrite(PWM_Channel9,box2);
}
void loop()
{  
boxes(0,160);
delay(1000);
