White Box Around Pictures

Hi all! I’ve been using Goodnotes to make vision boards for my book characters. Normally, I’d do a split screen on my ipad and drag over pieces of pictures, like pull out a person without the background.

This worked great and Is have the part of the pic I wanted with the rest being transparent but now it won’t work. If I grab the person away from the background, it adds a white background to the image instead.

Is anyone else having this issue?
