when the it is unpublished that means- Post status will remain as pending review or draft and for the published- Post status will be published. You can set the post status from Form editor->Post settings.
I'll try to test it more but I don't know what to test really.
If you can't tell me what's wrong I don't know what else to test.
I'll make another video but it'll be the same at some point the dropdown field disappears.
Please for future version is really needed: a batter way to submit values rather than 1 by 1 with single text field. And also the option to order them with drag and drop or sort them alphabetically etc.
