Since switching over to this new site I can't seem to submit a review because I'm unable to select a "star" rating under chemistry/incall location. Am I doing something wrong? I've tried multiple Web browsers and even my phone with all the same issue.

I have successfully submitted reviews on the new site.  I just started having this problem today.  Submit a ticket.
