Hi,
This was a design decision while working on the v5 - the idea is that since you are making changes after the object was baked, it breaks the relationship with the baking operation that created that object. (The change is actually happening in the eleFront Attribute component, not the Modify component).
That was probably a bit too purist of me, so I’ve added an option to the Attribute component where you can set it to maintain the bakename. It’s available in the 5.1.9 release.
