Where it is white, the picture isn't transparent. You have to remove the white pixel data for it to be transparent. It doesn't automatically do it, it just saves it in a way that transparent parts are saved as transparent.

How are you saving it? If you export for web you get the option with like… Png I believe to check the transparency box.

Use the magic wand an delete the background of the mc logo
