You just need to move your mouse to the arrow of the edit section of the article you want to undo

Then a list of orders appear (Classic Editor, History, Rename & Refresh) and you click "History"

In the history of the article you choose one of the edit that you want to remove it to the last edit and click "Undo" (like the picture above)

When you click "Undo", you will see the edit area, just click "Publish" button.

And write summary if necessary

P.s1: Sorry for the bad English =))

P.s2: I have to thank U Diego, since you answer his question for me =))
