Strange views behavior

Hi everybody.

I got a view with three pages and two blocks. When I edit something - for example delete a field in one of the blocks - it will disappear in all blocks/pages in a view, not only in a block that I removed the field in (same thing with others settings like title, format etc.)

I did however download some custom views examples... flexslider for example on just any module with views examples. And in this flexslider example view everything is working fine - when you modify one of the pages - only this particular page is modified not all the pages. WTF is going on? It's my second drupal install and same things happened over and over again. Did I forget about something?

Latest drupal 7.41 on localhost xampp.
