Shadow resize issue

[yellowbird]

I have this weird issue happening, (probably since last upgrade). I've attached a .zar. I take a photo with a white background. I then use the "select colors to enhance tool" to select the white background and right-click on the node to make it transparent. Then I add a shadow. If I resize it larger, the shadow usually resizes fine, but resize smaller the shadow is goofy. I've never had this problem before. I was playing around with it now and noticed sometimes if I just move the graphic to a different position on the page the shadow will snap back. The .zar has the original photo, the original with shadow which seems to have no problem, the photo with transparent background and shadow, and resized with issue. Thanks. (Designer Pro X v18)
