Can't Edit from a Duplicate Composition.
i have many compositions in my project.

when i duplicate composition folder 18, or just composition 18 then there is changing both composition. however i have changed texts in duplicated composition. then why Previous Composition changed.
There is Footage folder also may be linked with this composition.

I Dont know what is the deep logic in these compositions. i used it for minimal titles. But cannot copy or modification in duplicated composition from them.
Is there any way to duplicate and changing saparately? because there is changing in both composition automatically.
