Register page of this plugin is not responsive for mobile version

Hi,

When I open my website in my phone just to check the registration process on the phone browser I found that the tick button for terms and conditions is not visible. It is not responsive for the mobile version. Would you please make it responsive. Here is the image of my site when I open in the phone looks like this – https://drive.google.com/file/d/1u7nZ8VeJh3FiPhk6XkMrjCBqkwer5vbb/view?usp=sharing

Thank You
