[[Content Locker] Content Locker doesn't work with Mailerlite]

Hi there,
I've started to use Content Locker in free version and I really like it, but seems that MailerLite integration doest't work.

Under subscription option, when I fill the string with Mailerlite's api, I can't choose my list created in Mailerlite. The only option available il "null".

Is there a way to solve that?

Thanks so lot for support.

Here is a screenshot about it >>> Content Locker MailerLite
