[S] Teens in Scouts do not change into uniforms for meetings

This has been going on for months for me, but I thought it might have something to do with mods. However, I am currently playing with a game with zero script mods and it is happening again.

When my Sims are children, I have them join scouts. On Saturdays and Sundays, they go to meetings and change into their scout uniform automatically before they leave.

Once they become teens, they are still scouts and still go to meetings, but they do not change into their scout uniform. I can use the scout board to have them change into uniform, but they will change right back out of it before they leave and go in everyday clothes.

As I said, this is a brand new save. I removed the script mods before I started. There are some cc clothing mods, but they are for YA/A/E. If I take the mods folder out completely, the problem persists.

Also, I clicked "Report a Bug," but it brought me here to "Suggest an Idea." I don't know why.
