SolidWorks subassembly part that changes to a past modification date?

Hi all

In SolidWORKS 2015, I have an assembly when I open it, some parts of the subassemblies change at a past modification date (a few months earlier).

So I find myself having to rework  this assembly.

For information, these coins come from a family of coins, they are restored to their value in the family of coins.

To create copies of this part I use CloneComponents.

Thank you
