PolyGroup Edit effecting other objects than the one I am editing

[Gorgio0001]

I have been working on modeling in Unreal Engine 5. I stumbled upon a problem that hopefully someone here can help me figure out how to fix.

The problem is that when I change the size of an object using the PolyGroup Edit then it changes the size of other objects as well.
If it helps I have added an image that shows the difference between before and after.

First image = Before
Second image = After

As you can see in the images, the object that I am editing is not the only one that is changing size.

All objects that are changing are instances of the same mesh.

You’re editing the mesh, so all the other copies change.

If you only want the one you’re working on to change, you need to copy the mesh first in the asset browser, drag it into the level, then edit it
