Unity SpriteAtlas AssetBundle, how to exclude old sprites of spriteAtlas?

I found some problem on making spriteAtlas assetbundle.
The problem is why contain his sprites when make assetbundle for spriteatlas.
I checked off options “include in build” in spriteAtlas properties.
so I think it’ll be exclude origin sprites of spriteAtlas.
But the assetBundle contains spriteAtlas textures and his origin sprites.

I am using assetbundle browser for making assetbundle.
Although unchecked “include in build” option, this tool is checking depends-objects the sprites of spritesAtlas.

I am confusing about these.

I need any help.

Thanks.

do ignore Warning-Message in AssetBundle Browser for sprites of spriteAtlas.

if try moving these sprites to merge for sprites-duplicated, it makes this problem.
Thanks.
