2. Once installed, launch the app - Launch ModeMagic. and click on the 'My Badges' tab in the bottom of the left-hand side panel
3. Select the sticker you want to remove from the list of stickers in the left panel. Click on trash icon next to the product image from which you want to remove the sticker from the list of products on which the sticker is applied
To remove the particular sticker from all the product images at once, you can click on 'Remove All' to remove the stickers
3. Click on "Yes" button from the dialog box in the screen that shows up
If this does not work for you, check if you have modified the sticker-ed image by any chance.
