Hikashop Recaptcha plugin is overlapping email field

Hikashop Captcha is overlapping email field on mobile view. It’s not unusable, it’s just unsightly.
Tried:
- Patching the hikashop captcha plugin
- Adjusting settings in plugin
- Modifying in code inspector.
I believe that the problem is that, as the plugin settings line, the captcha is placed after the selected field. In the case, we have it after the email field. It behaves the same way regardless of what is selected. What I see is that the plugin placed the hika-recaptcha div in the hkform-group control-group hikashop_registration_email_line div, but the label and field classes have hkc-sm-4 and hkc-sm-8, so there is no room there for the repatcha (I think). Where and how do I fix this so it looks good? Thanks!
