Serial Monitor not printing correct output

It used to work fine, but for whatever reason this started happening. Can someone help?

It will sometimes print the same thing multiple times rather than just once. Sometimes it's missing letters.

here's the code:

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

}

void loop() {

Serial.println("");
Serial.println("----------------------");
Serial.print("Mount Lake Resort Date: ");

}

It looks like @manda123 is using the web editor/ arduino create

You may be filling the transmit buffer faster than the data can be printed. Put a short delay() in loop() between prints.

I've added a delay and the result is still the same. Any other suggestions?

Increase the baud rate (in setup() and serial monitor).
