customer_segmentation_analytics_shopify

Hi everybode,
I checked most of the airbyte usecases, an tried to implement some of them. I have a question about connection of dbt and the output of Airbyte's connection. Why in some usecase like the "customer_segmentation_analytics_shopify" in the lineage section, the connection between airbyte and dbt does not exist and it create a second table with the same name like the project I said. but in some picture of the usecase the connection between the output of dbt and airbyte is established and show in lineage section. Actually I have this problem, in my project in the lineage section the connection between airbyte and dbt established via a second table which is the same as output of airbyte. would you please explaine me?
Thanks
