After saving no post-status – Posts disappeare

Hi,

I have a problem with edit flow. After a post with a custom status is saved the first time or published and then is edited again, the status change button disappeares. So when the post will be updated or saved again, it has no status and it disappeares from wordpress. Also new edited published posts are not online anymore.

I deinstalled the plugin several times and installed it again. Nothing changed. I also deleted some statuses. But its the same. And while the plugin is deinstalled, a few posts are shown again but not all. So at the moment with and without plugin installed both times a few posts are not shown anythere in wordpress.

Do you have any idea how I can fix this?

Thank you!
