Easy Blog Create Date vs. Publish Date

When creating a blog post, we schedule it setting the Publish Date in the right hand column. It will publish on that date the the post itself will show the Create Date. It will also sort the post on the blog home page and another "recent posts" module by Create Date rather than by Publish Date. So, as an example, if we create a post today (12/31/16) and schedule publication next week (1/7/17) it will publish on 1/7 but will show on the post a date of 12/31 and list it on the blog home page and the Recent Blog Posts module on our site home page as if it was published on 12/31.

I've seen on other threads that this is a known issue that has been fixed but it still seems to be broken. Could you tell me how to fix it?
