twitter service bug

hi guys. I noticed a bug on the twitter service.

I registered two different accounts on my elgg application. I connected with the first account and I set the twitter username and password.  Then i logged with the second new account, I clicked on "settings" and then on "configure your tools" ( or something like that )... there I could see the twitter service already set up with the twitter account of the first user.

Could you please confirm this? I used mozilla firefox for the test.

How to solve the problem? Thanks in advance!
