MailChimp List not displayed

Hello,

I liked the plugin and was about to opt for PRO version. But unfortunately, I ran into an issue. Please help me fix it urgently so that I can go ahead and buy it.

I tried integrating mailchimp on our staging server and it worked successfully. But when I tried doing it on Live site (with same API), the list is not getting displayed. Also, the textbox has become small and unable to see any auto-complete list.

However, when I did “Inspect Element”, I was able to see all MailChimp List. Both staging and Live are using WordPress 4.8.4. Please look into it urgently.

Thanks.
