If you scroll down to the bottom, underneath “You may also like”, you will see “ADD BUNDLE TO CART AND GET 10% OFF!!!” which is what I’m attempting to remove.
Some bundle apps edit your theme code so looks like this is what has occurred here. If you had a back up of your theme then that might be easier to use to restore before the bundling app was installed. Otherwise you will need to edit your theme code and clean up the changes.
