How to disable your recaptcha?

Hi, ever since I updated to the version of Profile Builder with integrated recaptcha I have a problem. First of I don’t want your recaptcha field, because I don’t use your registration page, just the login widget for existing users. I already have a plugin that uses recaptcha and it has way more options to protect my site (not just your form, but contact form 7, anti spam and so on). Now I need a way to deactivate your recaptcha without it throwing a PHP error on frontend if the Keys fields in the settings are empty. I tried to delete the field itself but it still gives me these error messages on front-end:
“Warning
: Illegal string offset ‘recaptcha-type’ in
../wp-content/plugins/profile-builder/front-end/default-fields/recaptcha/recaptcha.php
on line
86 (line 90 and 125)
”
How do I disable your recaptcha completely?
