You can prevent this in the future by saving edited photos to a folder that you don't sync to Google Photos. It's on the left side of the page. Doing so opens a list of all of your photos.  Hover your mouse over the photo's thumbnail, then click the checkmark in its upper-left corner. Be careful not to select both photos in a pair of duplicates. It's at the top right corner of the page.
