Can someone test a glitch for me?

Just a bit ago, I was trying to do the Corrin and Azura quests when I noticed something odd. When I went to put Anna on my team, I saw that some units were at the top of my barracks when they shouldn't be. After a little testing, I found that setting someone to favorite 5 (light blue) makes them show up first when sorted.
Could someone else try to replicate this? I want to see if this is a thing.
