Google RECAPTCHA Images and Audio choices

I am using the Google RECAPTCHA plugin on the register form. The RECAPTCHA area asks me to check the “Are you a robot” box but then the Images block appears (aka – “Show me images with cars”) or the audio choice. I see in the set-up area that these are the only two choices – Image and Audio. Has everyone else seen this? If not, how do I got about making it the generic click of the box. Thanks all!
