New Base Game Hair Not Showing up [SOLVED]

Hello, I'm trying to update my override since it is outdated. I finished editing the base game, and I noticed the new curly hair that was recently added is nowhere to be found in sims 4 studio. I checked multiple times and haven't seen it either I'm blind as a bat, but it's not there....


I check sims 4 tray importer for more answers, and it's labeled as a mod not sure why. If anyone can know the answers, that would be much appreciated!
