Not Excluding Specified Posts

Hi Jeremy,

Wondering if you might be able to help?

We have two (very similar) web sites:
LakePath.com (real estate listings)
LeLacAppelle.com (housing development)

They are both running:
WordPress 4.9.8
Latest JetPack and All other Plugins
REST API Post Embeds v1.4.1
Same TwentyFourteen Theme/Child (with a few minor exceptions)
Same Plugins (with a few minor exceptions)

Overview/Issue:
LakePath pulls in Blog Posts from LeLac in the left sidebar. You helped me set it up for randomizing the posts every 10 minutes and it’s been working very nicely.

However, the Posts that I’ve excluded in the Widget Code continue to be displayed. I noticed this some time ago (maybe 4+- months ago), but never looked into it, so I don’t think it’s because of any recent WordPress or Plugin Updates.

When you get a chance, can you take a look at the Widget & Child/Function Code below and let me know what I’m missing?

As always, thanks in advance for any insight you might provide.

John
