I've tried editing one of my forms using Edge on a Windows 10 emulator and I was able to edit the form without any issue. Is it happens with all the forms or any particular form in your accout? Could you try checking edting the form using Google Chrome or Mozilla Firefox to see if you are able to edit the forms? Generally we recommend to use Chrome/Firefox to use with JotForm.
Please get back to us if the issue still persists. We will be happy to assist you further.
