Hi @Osan !
Is it possible that there were 6 subscribers that existed in your Shopify account prior to setting up your integration with Klaviyo? If so, that would explain why you are seeing fewer profiles in Klaviyo, because Klaviyo does not sync pre-integration subscribers from Shopify. These profiles would need to be manually imported in your Klaviyo account!
Another possibility is that you list was set to double opt in at one point, and there were 6 subscribers that never confirmed their subscription.
I would also suggest checking in your Shopify account to ensure that you integration is enabled! You can test this out by adding yourself as a subscriber to your Shopify account, and then checking to see that your profile was synced into Klaviyo successfully.
I hope this helps!
