reCAPTCHA setup in Elementor Form widget

I am using Elementor Pro with the OceanWP theme. I just added a reCAPTCHA field at the bottom of a Form widget. I obtained a Site Key and Secret Key for reCAPTCHA from Google and entered those into the Elementor>Settings>Integrations page. The form appears with the “I’m Not a Robot” checkbox, but when I try to use it the message “Please fill in the required fields,” with an “x” beside the reCAPTHA box appears. Also, the email field turns yellow.

The form works fine when I remove the reCAPTCHA field.

Also, is there a way to turn off the reCAPTHA feature that shows the “select all squares with vehicles, …” photo grid and just have the “I am not a robot” checkbox? The grid of pictures is really overkill for my needs.

Thanks for any help you can give me!
