so yeah in https://www.speedrun.com/rally_trophy/Russia#Novice (SS8) subcategory you can see three runs on the board but there should be also fourth one this https://www.speedrun.com/rally_trophy/run/z09nk18z

there is no difference in variables between the non showing run and the "3rd" place run the only difference actually is IGT, runner name and video link

What's weird is that if you change any one of the default leaderboard filters (even stuff that doesn't matter like "Videos - with only" or "Emulators - hidden"), you will see this run on the list.
Only the combination of the default filters make the run being hidden.
