I have jazzycat's newest trailer pack, unfortunately the trailers are not showing up. Is it my priority order or something?

Please provide your game.log as otherwise we can only guess.

Never mind, I have resolved the issue. It turns out I just needed to sleep so the freight market can refresh.

Ah, it's that problem. If you ever encounter it in the future and can't sleep (happens if you sleep too often), any action that quick times will fix it, be it using a ferry or a train, or quick traveling to your garage.
