There are "phantoms" of enemies on the client shuffled with the actual ones

That didn’t help.

It has the following sign:

And here is the info, but sorry for the colorization:

There are no phantoms on the server. Maybe you meant “killing an enemy on the server”?

Sorry for the disinformation, but I have just checked - at least killing an enemy in the debugger, with manipulating the “HideTime”, doed not make the phantom disappear. But one time I had watched the disappeared on my eyes phantom, probably by manual killing exactly the necessary enemy, but I am not sure.
