Some mailchimp fields not showing to match

Hi, since we updated the plugin, everytime we try to add a new feed we get an error when trying to match fields.

When we go to “4. Select the object to create when a form is submitted” and we select a list, not all the mailchimp fields related to the list appear to match with contact form fields. It seems it gets stuck in some part…

Can you help us to fix it?
