Hi ceyu,
I originally only intended to correct the tag (from man_made=entrance to proper entrance=yes).
Then I saw that (1) it is on a very unusual place (the very corner node of two buildings) and also that (2) there is another properly tagged entrance less then 5m away. 
That is why I assumed it was an entry error/duplicate and deleted it. Sorry!
I reverted my changeset (recreating the entrance on the original position), but additionally converted the tag from man_made to entrance.
As you are there “on the ground” maybe you could check if that corner position is indeed correct? 😊
