Gif frames stay on screen

[the_night_rose]

I edited gif and removed its background, but when i saved it (using File-->Export-->Save for Web) i noticed a mistake and i cant figure out how to fix it. Frames stay on screen instead of dissapearing, its below . Is this because i removed background? If so, please tell me how to export it without background so its not like this, I need it without background. Thanks for any reply.

Click on Each frame in the timeline then click on its Layer and delete its content

Do the same steps on All Frames

Only one layer is visible in one frame and if i delete others they dissapear from their frames. Girl is cut out in every frame and layers dont stay on screen in Photoshop, they are visible under other layers only when i export it.
