Why have my form tabs have disappeared?

How do I get my form tabs back?  I have tried duplicated the Form Tabs widget and also cloning the form.  Neither have worked.  This is a critical feature for my form.  Please help me get the forms back.  Thank you.

I got them back.  I noticed that I accidentally had '\' as the default value in one of my spinners, and that caused the form tabs to disappear.
