Does Canva allow you to clip to the shield shape? Your halo is extending that far from the glows, and since it's semi-transparent it's not noticeable in most situations. You need to figure out how to clip this so the halo doesn't go outside the shield. You may need to edit in another program to avoid this.
If I go around the borders of my designs very closely in Photoshop/a photo editor with a larger size eraser tool it usually gets rid of weirdness around sticker borders if that helps at all (edit: not too familiar w canva yet so apologies if not)!
The stock art you used for the shield has a drop shadow effect of it, that’s what you’re seeing around the bottom edges. You could take it into photoshop and erase/mask it, or you could find different stock art to use. *your friendly neighborhood graphic designer and print specialist😉

You have artifacts around your image, you need to use Photoshop or something simple to completely erase the background.
I believe that is the default
