I had this same problem. When I upgraded to version 3.1 the page attributes came back as well as many new features for screen width and menu placement.
That would make sense. However the #tag is always appended automatically even if you delete it and then refresh the page, even if you just come to the site without posting a review.
Yes the plugin appends #wpcr_respond_1 to the page URL whenver the page is loaded. I have added the anchor near the top of the WP page template as a workaround but this is not optimum. I would like to just get rid of the anchor altogether. I looked throughthe plugin code but I cant determine which entry for wpcr_respond_1 is the one in question as it is used extensively throught the code.
Can you tell me which code entry is driving this Append to URL or how to remove it?
