recaptcha doesn't work on email to modals

The recaptcha does not show up on the two email to options (to friend/enquiry) in the modal window when NOT logged in. When logged in it shows up. This is the exact opposite of how it should behave. I don’t care about the recaptcha for logged in users but it definitely should work for site visitors. Some robot could theoretically use this to spam people. Please let me know what to do or how to fix this. It’s a buddypress/bbpress site so that I use these login features instead of gd login features. Thanks.
