My coworker and I are working on the same confluence page. Not all the one I did were save. When I clicked on edit, my work shows up again but when I click save they are disappear.

Yes, clicked save won't save any changes that I did toward the second to last row and up. But when I clicked edit, all changes showed up again.

@Loan Welcome to the Atlassian Community

So when you edit the page your changes continue to show up but you are unable to save and publish?  Can you share a screenshot of what is occuring?

I was working on the 3 'parents' from the bottom of the page. When I clicked 'edit', all 3 parents file will appear. When I clicked save, only 1 parent appear. I tried to work on banking in the middle of the page and I was able to save with my work for banking but not parent.

Can you share a screenshot?  Did you happen to copy the content of this page into that page?
