Hey Ilan,
In the navigator, we see the names of the Expert Advisors. It might be the case, that you have changed some of the magic numbers from the Inputs. This will not display as a change in the Navigator. The name of the EA will not change, just the magic number inside.
The other reason that comes to my mind is that you have that EA running on another MT on another PC/VPS. And if you are logged in there, that EA results will show in this MT that you have captured in the screenshot.
