I know this works but why can't I submit it? Is this a bug or am I missing something?

This happened on the previous code challenge as well. It won't let me alter the code on line two that's already written, and I can't use let to restate the abbreviatedDays Variable. Am I missing something here?

app.js 
const daysOfWeek = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
let abbreviatedDays;

// abbreviatedDays should be: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
// Write your code below

let abbreviatedDays = daysOfWeek.map(day => day.substr(0,3));

Since abbreviatedDays is already declared, you just need to use it.

abbreviatedDays = daysOfWeek.map(day => day.substr(0,3));

That will pass.
