"I've solved This myself " hidden

[Sumal V]

Hello there, The "I've solved This myself " button is hidden sometimes, this made me provide a solution to my own question and accept that, but as soon as I pasted my solution, this button reappeared. It has happened a couple of times to me before. And when I solve a question myself, the green coloured tick mark doesn't appear. This makes other users waste their time in looking into my question and suggest answers. Hope this will be fixed (if I'm not the only one experiencing this ;) ) Thanks
