An empty Jurors page means nobody has been attached to that competition's jury panel yet. The page exists because the competition has a jury section, and the section is filled in separately from creating it, so the two can be out of step for a long time. It is not a loading fault and refreshing will not populate it.
What you are seeing, and where the button goes

The page shows the line "No jury members available for this competition" and a View Our Jurors button. That button does not go to this competition's panel. It opens uni.xyz/about/jurors in a new tab, which is UNI's general roster of jurors across the platform, not the people judging the competition you were reading.
On some competitions the sidebar entry itself is replaced by an outbound Jurors link to that same roster, so selecting it takes you off the competition entirely. If that happens, you have not lost your place: use your browser's back navigation, or the tab it opened.
Why panels are often not there
- The panel has not been announced. Many organisers confirm jurors after registration opens, and some only shortly before evaluation. The section goes up with the competition; the names arrive later.
- The panel is not being published. Some competitions never list their jurors publicly. Nothing on the page distinguishes this case from the one above, which is the honest answer to "will it be filled in later": on the competition page, you cannot tell.
Being listed is not the same as judging
The jury section is a published description of the panel. It is not the mechanism that gives jurors work. Somebody can be shown on a competition's jury page and have no entries assigned to them, and evaluation can be under way on a competition whose page shows nobody.
That gap matters if you are a juror yourself. Your juror dashboard is empty covers it from that side.
What an empty panel means for the leaderboard
The jury column on a competition's leaderboard is built from the jurors attached to its jury section. When nothing is attached there, no jury scores are gathered under that competition and the leaderboard shows community numbers only, with the jury column removed rather than left blank. See What each leaderboard column means.
If you want to know who is judging
Ask the organiser through the competition page rather than waiting on the section to fill. Contacting competition organizers and the UNI team has the route. An unannounced panel is not a sign that the competition is not being judged: evaluation runs to the published schedule either way.
