Giant checkbox on top of text on WooCommerce

Hi!

The plugin works fine for Blog Comments. But on Woocommerce, rather than a small checkbox next to the agreement text, I get a giant checkbox centered on top and in middle of the text, so it can’t be read.

Here is a screenshot: https://www.foreverbarcelona.com/wp-content/uploads/2018/04/Screenshot_042718_065044_AM.jpg

Any help will be appreciated.
Thanks,

Marta
