It's seems like the court, own kingdom, does not work as intended, when it comes to new vassals. The log message claims, that a certain lord have been exiled, and have joined my kingdom, but he does not appaer in my court. Even had 3 exiled lords apply to my kingdom, but they don't show up. Sometimes, when entering the court multiple times, then I can make one of them appear. I can also decline a lord multiple times, because even when I deny their application to my kingdom, they keep showing up on the same day, when entering/exit court. Often they also leave their wifes hanging out in court, even when I have denied their lord (more ladies for me, but it seems like these wifes take up a court spot). So far I have not seen applying lords stack up in my court, only 1 at a time, if any at all, even though I know they should be there.
