LiquidCrystal_I2C lcd(0x27, 16, 2) Two place digits?

I would like to know what I am missing in the code, when it prints out on the LCD display, it is only printing out one digits. (“0:0:0:0:0”).

I like to know how to make a print out and run the numbers like this.
("00:00:00:00")

Has something to do with this line.
h=0;
lcd.print(h);

#include <LiquidCrystal_I2C.h>
#include <SoftwareSerial.h>

int h,m,s,ms;


LiquidCrystal_I2C lcd(0x27, 16, 2);

int start = 8;     // the number of the pushbutton pin
int Stop =  9;      // the number of the LED pin


int buttonState1;         // variable for reading the pushbutton status
int buttonState2;         // variable for reading the pushbutton status


void setup() {
Serial.begin(9600);

pinMode(start, INPUT);
pinMode(Stop, INPUT);

lcd.begin();
lcd.clear();
lcd.print("Time Stop");
lcd.setCursor(0,1);
lcd.print("00:00:00:00");
}


void loop() 
{
buttonState1 = digitalRead(start);
buttonState2 = digitalRead(Stop);
Serial.println(buttonState1);
Serial.println(buttonState2);
 
if(buttonState1 == HIGH) 
{
  ms=0;
  s=0;
  m=0;
  h=0;
  lcd.setCursor(0,1);
  lcd.print(h);
  lcd.print(':');
  lcd.print(m);
  lcd.print(':');
  lcd.print(s);
  lcd.print(':');
  lcd.print(ms);
  lcd.print(" ");
  delay(250);
}


if(buttonState2 == HIGH)
{
  ms++;
  delay(100);
  if(ms==10){
    ms=0;
    s++;
  delay(100);
 if(s==60){
    s=0;
    m++;
    delay(100);
    }
  if(m==60){
      m=0;
      h++;
   delay(100);
    }
  if(h==1){
      h=0;
      m=0;
      s=0;
      ms=0;
      ms++;
    }
  }
  Serial.println();
  lcd.setCursor(0,1);
  lcd.print(h);
  lcd.print(':');
  lcd.print(m);
  lcd.print(':');
  lcd.print(s);
  lcd.print(':');
  lcd.print(ms);
  lcd.print(" "); 
}
}

This example sketch illustrates how to add a leading 0 if the number is less than 2 digits. Adapt to LCD.

// By C Goulding
int h = 4;

void setup()
{
   Serial.begin(115200);
   if(h < 10) // if h is single digit
   {
    Serial.print(0);  // add 0 pad
    Serial.println(h);    
   }
   else // h is > 1 digit
   {
    Serial.println(h);
   }
}

void loop()
{

}
