Problem passing one test in Pomodoro Clock

Hi.
I’ve -almost- finished my Pomodoro Clock, and that means, almost the Front End Library certification…yay !!!
BUT…there is one test I cannot figure why I’m getting wrong. This is what I get;

#Timer

  1. When I click the element with the id of “reset”, any running timer should be stopped, the value within id=“break-length” should return to 5, the value within id=“session-length” should return to 25, and the element with id=“time-left” should reset to it’s default state. Error: Default timer label was not properly reset

Here is my codepen: https://codepen.io/eday69/pen/QBQRwR?editors=0110

Any help will be appreciated.
Many thanks !

Many thanks !
I did try several times and kept failing the mentioned test.
Tried again this morning and failed the first time, but tried a second time and it has passed.

It seems it passes/fails randomly … =(
