Small bug on the most recent update of Photoshop CC 2015, the dropdown menu for "Set:" appears underneath the "Done" option. It is still usable, but I doubt it's supposed to look like that. Looks like there's just too much padding to the left.
Thanks for the info and the screenshot. Unfortunately, I cannot duplicate this on either my Mac or Win machines. Could you share your OS and monitor resolution with me? Do you have any other display setting which might impact these results?
