I see many of these files "${system_uuid}.${target_name}.dg.profiles.xml", sometimes several per days, with different ${system_uuid} values.
And they contain my Execution Parameters.

Now I realize that my ECF has no UUID. So apparently EiffelStudio creates a new one behind the scene each time.
I don't remember having this issue with previous versions of EiffelStudio.

I added a uuid to my ECF and now it works.
