Chris - I deleted also the captured url's, and took an extra step I added manualy those captured 404 url's which faulted.
For example : " /page-title/?nb=1&share=facebook " redirect to facebook
Same with twitter, pinterest, etc
And also if you disable the plugin, and re- activate you need to doit again..
Temporary its ok.. Till wordpress jetpack developers fix that incompatibility issue..
Hope it will work for you as well.
