Related products being auto generated by category

I just discovered that instead of displaying all of the manually selected products to show up on our product pages, our product pages are now showing random products from same category instead.

I have not set up these products to show related products by tag or category, only manually selected. But this is being ignored. If I had to guess this happened late last week when we upgraded to the latest version of wordpress. Please advise
