Problem in Polls Section

Polls section is not working properly, five members voted same answer for a poll, but it doesn't reflect that five members voted for this poll, however it is only showing that only 1 member answered for this poll. Even though if some one click on another option for the same poll, it does nothing.

Please see the attached screen shot.

Thanks in Advance...!!!

unable to reproduce

any solution...!!!

 no solution, i am not able to reproduce your error.

Try to re-install the polls module.
You say five people, five unique members? or five different users (test accounts) from the same computer?

 yes five unique members, but from the same system
