Article placed into multiple sections appears multiple times in "All articles"

Following on from https://support.zendesk.com/hc/en-us/community/posts/8371476981018

I noticed in “All articles” that the article I placed in multiple sections appears many times on this screen (placed in 10 sections and appears 10 times on the list). 

I refreshed thinking it's a caching issue however it still appears multiple times. When you click on each one, it's the same article.

I tested other articles and any article that you add to more than one section will appear multiple times on the “All articles” screen.
