You didn't mention which version of Flow you are using, but this issue 
is fixed in master (3.0b1+), see [1].

Unfortunately it's a rather large and breaking change so we couldn't 
backport it to older branches..
But you could always create your custom Checkbox-Viewhelper adjusting 
the behavior.

Fortunately there's an easy work-around for your case:
Don't use the "checked"-argument but bind the checkbox to the 
"visible"-property of your entity. For the "new" form you then need to 
create a new instance manually and assign it to the view.
I created a little snippet to make it clearer [2].
