I have an task for my class where we have to make 2 LEDS blink alternatively using a pushbutton. I've figured out how to do the blinking and alternating but from time to time one of the led would go twice in a row instead of the other led blinking. Need help figuring out what's making it do this in my code. I'm using Tinkercad with Arduino UNO.

int buttonPin = 7;
int redledpin = 11;

int orangeledpin = 12;

void setup() {
  pinMode(buttonPin, INPUT);

  pinMode(11, OUTPUT);

  pinMode(12, OUTPUT);
}

void loop ()
{
  {
  if (digitalRead(buttonPin) == HIGH) {
  
   digitalWrite(11, LOW);

    digitalWrite(12, LOW);
  }
 
   } else {
   
  digitalWrite(11, HIGH);
   
  delay(500);
   
  digitalWrite(11, LOW);
   
  delay(500);
  }
  
   if (digitalRead(buttonPin) == HIGH) {
   
  digitalWrite(11, LOW);
 
    digitalWrite(12, LOW);
   }

  } else {
    
 digitalWrite(12, HIGH);
   
   delay(500);
  
   digitalWrite(12, LOW);
  
   delay(500);
  } 

  if (digitalRead(buttonPin) == HIGH) {
  
   digitalWrite(11, LOW);
  
    digitalWrite(12, LOW);
  
  }
 
}

Backticked code, added a language specifier and corrected typos.
