I had similar problems with Website title and Website URL and reported them here:
By some miracle, it eventually stuck but other people have reported still having the same issue.
I'd like make a modification to my URL but I'm afraid to mess with it. The original intention was to link to my projects on GitHub but they are now mixed in with my collection of >1500 forked repositories for pull requests that haven't been merged yet.
I never tried to add personal text so I can't say whether that was a problem in my case.
What happens if you only add the personal text and leave the website fields empty?
