Click counter using SparkFun Qwiic Twist

I wrote the script below in order to count the number of times that I press the SparkFun Qwiic Twist. But when I press the button, I get series of running numbers on the Serial Monitor and not a counter incrementation by 1. Any ideas how can I solve it?

Script:

#include "SparkFun_Qwiic_Twist_Arduino_Library.h"  
TWIST twist;  
int twistPressCounter;

void setup() {
  twistPressCounter = 0;
  Serial.begin(9600);

  if(twist.begin() == false)
  {
    Serial.println("Twist does not appear to be connected. Please check wiring. Freezing...");
    while(1);
  }
}

void loop() {
  if(twist.isPressed()) {
    twistPressCounter++;
    Serial.print(twistPressCounter);
}
 
  Serial.println();
}
