How to control four servos with two buttons

I tried adding separate angle variables. The result is still the same. I changed the print for buttons. Nothing change. It showed that one button that controls two servos is functioning and the second button for the other two servos didn't.

#include <Servo.h>
#include <ezButton.h>


//constants won't change
const int BUTTON_PIN = 7;
const int BUTTON_PIN2 = 6;
const int SERVO_PIN = 9;
const int SERVO_PIN2 = 8;
const int SERVO_PIN3 = 5;
const int SERVO_PIN4 = 4;

ezButton button1(7);
ezButton button2(6);
Servo servo;
Servo servo2;
Servo servo3;
Servo servo4;

// variables will change:
int angle1 = 0;
int angle2 = 0;
int angle3 = 0;
int angle4 = 0;

void setup() {
  Serial.begin(9600);
  button1.setDebounceTime(15);
  button2.setDebounceTime(15);
  servo.attach(SERVO_PIN);
  servo2.attach(SERVO_PIN2);
  servo3.attach(SERVO_PIN3);
  servo4.attach(SERVO_PIN4);

  //servo.write(angle);
  //servo2.write(angle);
}


void loop() {
  button1.loop();
  button2.loop();

  if(button1.isPressed() ) {
    Serial.println("The button1 is pressed");

    // change angle of servo motor
    if(angle1 == 0 ) {
      angle1 = 90;
      angle2 = 0;
    }
    else {
      angle1 = 0;
      angle2 = 90;
    }

    if(angle2 ==0) {
      angle1 = 90;
      angle2 = 0;
    }
    else {
      angle1 = 0;
      angle2 = 90;
      
    }

    //control servo motor according to the angle
    servo.write(angle1);
    delay(50);
    servo4.write(angle2);
    delay(50);
    }


 if(button2.isPressed() ) {
    Serial.println("The button2 is pressed");

    // change angle of servo motor
    if(angle3 == 0 ) {
      angle3 = 90;
      angle4 = 0;
    }
    else {
      angle3 = 0;
      angle4 = 90;
    }

    if(angle4 ==0) {
      angle3 = 90;
      angle4 = 0;
    }
    else {
      angle3 = 0;
      angle4 = 90;



    servo3.write(angle3);
    delay(15);
    servo2.write(angle4);
    delay(15);
    }
 }
}
