Wrong date applied to posts when viewing all posts under Named Category

When viewing a category, each post in said category displays the wrong date and “Uncategorized”(other categories display date and category correctly).

example: November 30, -0001 Uncategorized (Note the year. All posts in this category display identically)

When a specific post in said category is clicked on and displayed, it shows the correct date and category:

example: June 15, 2015 CAFP Parenting Strategies

Running 4.2.2

URL: https://blog.cmcafp.com From sidebar select “Parenting Strategies”

Attempted so far:
1. renamed “Uncategorized” then deleted.
2. Changed time zone: City and then UTC-4 for local time – neither effected any change.
3. Created new category and assigned same post – no change.

No posts are allocated to “Uncategorized”

Not sure where to go from here. Any suggestions would be greatly appreciated.
