Odd data saved to CFDB on the ReCaptcha field-not spam

Hello,

I’m testing a new simple contact us form which I’ve created in Contact Form 7 with it’s own recaptcha field. On submiting the form and checking the recaptcha field I get odd gibrish data in the CFDB :

The title of the field is : g-recaptcha-response

I can’t delete this field and I need to delete all the row in order to get rid of it.

The site is not “on air” yet but I need to know how to solve this issue, or not to use the recaptcha field.

Thank you.
