Video made from matinee shows preview level

hello guys, I am in huge trouble. I need this video for my showreel. But when I click on movie button and make video i get this.

and my actual scene is this,

my matinee is already linked to the level i.e my village level through level blueprint, but my final video(also my play window) I am getting this default or something project with it. How can I get rid of this??

Ok, I found something. I saw that there are some persistent level in my project. But it doesnt show in my content browser or on unreal startup. How can I delete those level. I am kind of learning now, so please help me. :frowning:
