I have found where the bug lies, but not how to fix it.
The number of duplicate posts that load are equal to the number of Drafts I have saved. If I delete all drafts there are no duplicates. If I have 3 drafts, there will load 3 duplicates.
Included. Please let me know how you fix it as well.
Update: I have now updated to 2.1.0. Problem still persists.
I am running on 2.0.0, and I cleared and deactivated all server and browser caching and the problem persists.
