Most recent blog post from RSS not showing up for unregistered user

We have our company blog pull in on our community homepage. We just posted a major piece of news on the company blog earlier this week, and when I logged in yesterday, I saw that the news had pulled into the community homepage, as expected.

However, this morning we've discovered that you cannot see that most recent piece of news unless you are logged into the community. You can see other, earlier pulled in blog posts, but you can't see the most recent one unless you are logged in.

LOGGED IN, THIS IS WHAT I SEE:

NOT LOGGED IN, THIS IS WHAT I SEE:

One more factor: we also added a PHOTO to the Product News post after it drew into the community. We added that yesterday. You can see that photo when you are logged in (top image, on right) but not when you are not logged in (bottom image, on left).

Why could this be happening? I've checked Everyone permissions, and they seem fine. I've checked RSS settings and they seem fine. This might be a case for Support, but I thought I'd post here first in case I'm missing something obvious. Am I missing another error?

Thanks!
