There's a time limit on editing posts. Perhaps you had exceeded the limit when you tried the second time. Admittedly, that doesn't explain why it returned after you deleted it the first time.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
