Duplicate custom collection

Hi!
I’m trying to duplicate an example of a custom collection and change the links, but every change I make automatically applies to the whole app, which completely defeats the purpose.

Is there any way to duplicate them without making all the changes automatically apply to everything?

Thanks!

Bonjour @Clarisse_Audigane,

Je parle français si tu as besoin. It’s difficult to understand your problem, maybe can you screenshot the page in question and also tell us how you get there from the main tab.
Here is a conjecture : you are in a detail screen and if you change one element in a detail screen then the same change will apply in all the similar detailed screen. FYI this is not the cas with New screen.
Please share more element so that we understand better your problem and if this problem is a show detail screen issue or not.
Bien à toi
