Two user-input prompts being printed at once, and only one scanner input. Why?

Question

This is an exercise to use Zeller's algorithm.

When I run the program, and after I enter a value for the first user input ("Enter a year: ") and hit "return", the program prints the third user input prompt as well as the second, like this:

Enter a year: 1996

Enter the name of a month: 

Enter in a date in a month. Ensure that the date
is within the range of days (eg. Do  not enter '30' if your month is February):
enter code here

Is this something to do with the third prompt being inside a do-while loop? Thanks in advance!

Here's the whole program:

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    
    //User enters a year.
    System.out.print("Enter a year: ");
    int year = input.nextInt();
    int k = (year % 100);
    int j = (year / 100);
    
    System.out.println(); //New line for legiblity on the console;
    
    //User enters a month.
    System.out.println("Enter the name of a month: ");
    String userMonth = input.nextLine();
    String month = userMonth;
    int m = 0; // This will be reassigned, in the switch statement, with the integer value of the user's month.
**enter code here**
    switch (month) {
        case "March": m = 3;
                break;
        case "April": m = 4;
                break;
        case "May": m = 5;
                break;
        case "June": m = 6;
                break;
        case "July": m = 7;
                break;
        case "August": m = 8;
                break;

                break;

        case "November": m = 11;
                break;
        case "December": m = 12;
                break;
        case "January": m = 13;

    } 
    
    System.out.println(); //Just for ease of legibility on the console.

                + "is within the range of days (eg. Do  not enter '30' if your month is February): ");
