So I really don't understand what you just said, but I'm going to take a shot in the dark and guess that you are having difficulty searching for a mission that hasn't received any reviews yet.
The most likely cause is that you aren't set up as a reviewer, or perhaps you were but clicked the stop reviewing button. In either case, the solution is to click on the Become Reviewer button at the bottom of the Foundry mission list window and agree to the EULA. This will show any missions that haven't received 5 reviews yet.
If you are asking something else, I apologize and please clarify.
I've never been a reviewer, and I've been able to see every ones with stars, and without stars. Then today I was browsing both tabs clicked back to the brows all tab, and notice I can't see the ones without star ratings, and I thought that was unusual. Then I'm guessing it figured out I'm not a reviewer now. Plus I was looking for my own, and couldn't find it, and thought it didn't get on there even though its says it did.
