One of my tables disappeared from "Edit Mode"

One of my tables disappeared from "Edit Mode"

Hi
 
 
I edited a field type in my "Create Invoice" form in my Frozen Foods application and the form has disappeared in editing mode.
 
All I did was add an Initial Value in the field property for the "Country" field, and the form no longer shows up. I can see the view for it though.
 
Can someone fix this? I have given edit access to support.
 
Thanks
