I've found a series which has the wrong title.
https://www.mangaupdates.com/series.html?id=142226

The title is listed as "Shippo-gai no Koo-sensei" with "Shippomachi no Ko-sensei" as alternate title. But the official series page at the web of Office YOU has a top image when it can be read (in romaji) that the correct title is "Shippomachi no Ko-sensei", though stylized as "Shippomachi-no-"ko"sensei".

How can the title be corrected?

Thanks!
