Graphical error in MT4, bollinger bands

Hi.

I have a issue using bollinger bands and wonder if anyone could tell me how to fix it.

In the image below see the lines above price chart, what are they and how did they get there?

Thanks alot!!

Do you know what those can be used for? what does they represent?

Sincerely

Edit: Are they just to add extra bands?

yes
