Why does a source build doesen´t update CL (Change List) Version of editor dll.s when changing it in Engine\Build\Build.verion and rebuild

I have a problem with changing the ChangeList version of a source buillds dll´s.

I tired to modify : Engine\Build\Build.verion

And run a “Rebuild” in the Engines UE4.sln

But after that the CL line in the dll´s properties doesn´t change.

Thank you in advance.
