The scenario is that the Marketing Lists (and the list members/Contacts) from your CRM do not seem to be created in Mailchimp, even though the log files said they have been synced.
Sync Profile check:
Make sure that you haven't enabled the Filtering and Segmentation as Marketing Lists will not be created as separate Group(s) in Mailchimp, rather, it will create new Groups based in the Segmentation criteria set in Step 5 of the Sync Profile.
Option 1: CRM Marketing List Sync Only
If wanting to sync only your CRM Marketing List(s) with list members or Contacts in it then select only the Marketing List feature only in Step 1 of the Sync Profile. (See screenshot below)
When the sync runs, these Marketing Lists will be created as separate Group(s) in Mailchimp and the records will be added to them or updated on the existing ones.
Option 2: New Group(s) created by Filtering and Segmentation feature Only.
Our Filtering and Segmentation feature is very popular with our subscribers today.
If wanting to create Group(s) without manually selecting Marketing List(s), In Step 1 of the Sync Profile, you will need to set the Marketing List Sync to "None" so that the Filtering and Segmentation feature will base its record lookup to your whole CRM database.
Next, in Step 5 of the Sync Profile, set your Filtering criteria per Segment. And once again, please note that per segment will create a Group in Mailchimp. Let's create an example using the screenshot below.
Example, based on the filtering criteria below, the Segment Name "T1" will create a new Mailchimp Group named "T1" then record under that created Group will be those Contact type records with Type 1 Program. Same works in the next segment.
