Content disappeared after saved

Hi team,

I’m writing release notes for upcoming version. During documentating, I saved and published periodically.

After finished, I reloaded the page and found that some of my content disappeared for no reason.

Even didn’t see any content in history to revert.

Please help check and recover the content.

Thank you,
Dung H. Nguyen
