Default value is not auto-generated when content is used

Hello, i have an edge E1 with a property created having a default=“sysdate()”;.

I properly observe the field creted is auto-generated with:
create edge E1 from x to y set anyfield=“anyvalue”

But the field created is not auto-generated with
created edge E1 from x to y content {“anyfield”:“anyvalue”}

unless I implicitly set in the content JSON.

is this normal?
