Sorting a Parent Throws - An item with the same key has already been added

i know the bug was resolved in umbraco 7. but i'm using umbraco 7.1.8 and some parents in my umbraco tree are throwing the error when right clicking - Sort

i've deleted my temp directory and let it rebuild
restarted the app pool
touched web.config

but still can't get around it. any ideas?

update: i've noticed it's when attempting to sort a parent with child documents that also display this error...

its not document type related because other child pages of the same doc type are fine.

i'm also unable to delete these nodes.. so anyone know of a script to nuke this?
