Rating stars appear after 5 seconds delay

Hi there,

I have installed the Comments plus plugin (in my developing site), but the following problem occurs: When i select the WordPress Tab, the stars for the rating do not appear immediately; instead, they appear after a 5 seconds delay. (See the attached image)

Except from this problem, i would like to ask if it is possible for the facebook, twitter or google users to be able to rate, except from leaving only their comment.

Thank you in advance,
