Components are missing when previewing form

This is very annoying. I add components to my form and they don't show up in my preview. It happens all the time with the form separator widget and now it's happening with the file upload component.

This is my screenshot while making the form:

Here is my preview (you can see the form separator and upload button are missing):

What am I doing wrong all the time??

I was not able to reproduce the issue on a cloned version of your form. Note, that Form Separators widgets are properly loaded as the red lines. I have checked the Preview window in different browsers and Upload fields were fine.

Can you please re-check the Preview option using some other browser? Does it make any difference?

I think I figured out what the problem was. There were random conditions on my form (probably because I clone forms). So some fields were not showing up because conditions were moved around to random objects in my form.

We are glad to hear that the issue is fixed. Thank you for your update.
