Missing Forms in Admin

Hi I have a strange issue. I ahev set up various forms about 10 so far and still need to add more as its for a multilanguage site. In any case the forms are all working correctly but now when i have returned to the wp admin to add more forms they are not being displayed. However i have gone to the frontend pages and the forms are there working correctly. What can i do to see them again.
