wrong anchor tag on ww.wp.xz.cn

On this page, there is an anchor in the first line here
https://ww.wp.xz.cn/support/article/network-admin-updates-screen/#upgrade-network
it points to https://ww.wp.xz.cn/support/article/network-admin-updates-screen/#upgrade-nework which is 1) wrong (missing T in network), and 2)pointless since it takes you to the title of the same section half a line up.

The page I need help with: [log in to see the link]
