Component changes orientation from preview

I have been having difficulty with the component placement during assembly. 

Here is a simple example:

Assemble an additional component to an existing assembly, in the case a simple bracket.

Mate 2 surfaces, insert a pin into a hole and the SHOW COMPONENT IN ASSEMBLY WINDOW view has the component correctly oriented (and I understand that it is only partially constrained).

Select the Done green check mark and presto ... oh wait .... that's not what I wanted, I wanted what was in the preview.  Now I have to go back in a redefine the placement and add the additional constraint.  If it had shown me that while I was in there the first time I could have saved some time.

Why is that?  Seems like a bug in the component assembly routine.

Can any help me (other than saying "fully constrain in the first place)?

I hate when that happens.  I got no solution but I can give you empathy.  And as a wise guy once said, "fully constrain in the first place"

I recommend you disable the "assumptions" that Creo makes for you when partially constraining components.

I also don't want to use these partially constrained components as a type of a "mechanism" substitute.  If it is meant to be dragged, then it should be defined with a proper mechanism connection.

My config.pro:

comp_placement_assumptions no

enable_implied_joints no
