For some reason people have started to make up circulation numbers out of nowhere, posting them on Weblio Pages and in Yozakura's case, in its own Wikipedia page, linking to a Natalie article with nothing related to that fact. They have also done this for MASHLE.

Yozakura Wikipedia page with the same information as above:

Article used as source, which is false:
本日8月26日に発売された週刊少年ジャンプ39号(集英社)にて、「ポロの留学記」の権平ひつじによる新連載「夜桜さんちの大作戦」がスタートした。

Any of this information is
completely fake until official statements are given by Shueisha themselves.
EDIT 17 minutes later: I deleted that stuff from the Wikipedia JP page. Dunno even if I did it properly, but anyway.
