Level Blueprint reset everytime I initiate Unreal

I´ve only created interaction with Event BeginPlay > Create Widget > Add to Viewport.

Just that and while i didn´t close the Unreal, the project was just working fine. But if a close it and re-open it, the Level Blueprint was reset.

I don´t know why this. Could someone explain to me?


Can you make sure you have the right Level open and saved it? Double click it in the Content Browser to be sure.
