Thanks! Being able to see the site directly is always super helpful for troubleshooting. ??
I wasn’t able to replicate this issue on a test site running Sketch – only a single set of sharing icons is displayed below portfolio projects, as expected.
Are you using the default implementation of the Jetpack sharing icons or did you add any Jetpack code directly to the Sketch theme, or have you made any other changes to the Sketch theme files? If you have made these sorts of theme changes, try undoing them temporarily to see if that solves the issue. If it does, add back your changes bit by bit to find the culprit. (If you have made theme file changes, I would highly recommend using a child theme so your changes don’t disappear when you update the theme.)
Another troubleshooting technique would be to deactivate all your plugins and see if the duplicate icons go away. If they do, then reactivate plugins one-by-one to find the culprit.
Let me know how it goes.
