Hello Toufiq,
If i use the Carousel Addon and change the Content Margin of one Carousel Item, it changes all other Items too, even if another value is set.
It does not matter if i use the "+Add" Button or "Copy" Button.
Item 1 Content Margin is set to 360px left & right:

Item 2 Content Margin is set to 460px left & right. This overwrites the 360px entries in Item 1 and all other Items:
