Duplication issue

Hello there, I dont understand why, when I duplicate or copy paste an object, the properties are still linked.
I copy paste the object ‘A’. I rename the second object ‘B’. I open the blueprint of ‘B’ to rename some trigger that I made on ‘A’ before the copy.
After renaming the triggers ( ‘b’ ), I go back to ‘A’ blueprint and the ( ‘a’ ) triggers are now also named ‘b’ !
I search to unlink them but it seams they share the same blueprint… :frowning:
If someone know what it is… help :wink:
