Question Post Widget shows when editing but not on page after save

[Patience]

I've been trying to add a post widget and on the query tab adding a term under the "included by", and adding a category into the term. As stated in my title, everything shows properly when editing but after I update and save my work, pull up the live page, nothing shows. Where can I start troubleshooting this? My Google searches for help haven't come up with much.
