Editing and saving works as intended when I checked it on my end.
I would recommend you give it another try, only this time, try the following suggestions:
1. In case you're using a different browser, use Chrome.
2. If you're currently logged in, logout of your account > log back in > then try editing your form.
3. If all of the above won't suffice, clear your browser's cache and cookies.
