Mailchimp Plugin Sign up form

Hi,
I’m using Mailchimp Plugin for WordPress Version 1.2 | By MailChimp and Crowd Favorite, and I can’t display in the signup form either drop-down menu and multiple choice that I set up in Merge tags in Mailchimp List setting. They appear like a text field https://www.screencast.com/users/JuriT/folders/Jing/media/4cb8e4db-417c-4ebd-8556-304680a00434
here is the plugin settings https://www.screencast.com/users/JuriT/folders/Jing/media/c8d1da85-b8a4-4c1b-b0e6-5c96030b0865
I’m wondering if someone can give me some advices.

Thanks
