Library Part Maker - Custom Door Handle Orientation

[enz_mc]

Hi, I have encountered a minor issue when defining the custom door handle orientation when using the Library Part Maker 27.

According to the help guide, the origin of the morph line defines the anchor point, and the direction of the line defines the handle direction like below:

However, when I did it, it seems the direction has been mirrored. I also tried mirroring the morph line (horizontal axis), but to no avail.

Has any encountered this? Is this a bug? 

Thank you.
