Issue with exercise mark erasing/rewinding code

In some of the Front End Career lessons, whenever I get to the exercise mark, it “rewinds” to a prior code and erases whatever setup was done by the instructor. One example is this lesson. It does away with Per’s setup code in HTML and CSS. This started happening recently., I’ve tried with multiple browsers and no extensions and I still have the same issue. Other examples of this happening is the “Guess the expression - truthy or falsy?” lesson and the “Write your first function parameter” one.

Here’s a video I captured of this issue.

Hey @RenanMDP, is the example link you have directing to your note? Seems I can’t access it as you might have it set as private. What could potentially be happening is that you have some saved notes (which are versions where there is no code in the editor), that persists when you hit that point. So it’s overwriting what you wrote with a previous code state. This shouldn’t be happening I think so it’s a weird one.
