Copy activity into Lakehouse with schemas enabled

Hi, I am trying to understand, if I do anything wrong, or there is a actuall issue/bug in Copy Activity in Fabric.

I am trying to copy a table where source is on-premise SQL Server 2019 and a target destination is a Fabric Lakehouse with enabled schemas (preview feature).

Expected behaviour: In the target lakehouse and schema will get created new managed table based on name specified in copy activity.

Actual behaviour: Schema argument is ignored by copy activity. It creates a schema based on table name and no managed table gets created.

And here what gets created inside the Lakehouse

Many thanks for any assitance.
