Unable to delete a field on the form

My form has separate data entry fields below the submit button but they don't show up in the builder so I am unable to delete them.

I changed the layout in order to delete the sections. This ticket can be closed but this is still a system bug.

Could you please clone the form and then switch back to the layout in which you were experiencing the issue? We can then take a look and escalate the issue to our backend team.

Looking forward to your response.

Thanks.
