Default Variables Visible In Actor's BP

All of the sudden, Unreal’s default variables and event dispatchers have become visible in all of my actor’s blueprints. (For example, CustomTimeDilation, and everything in the Rendering, Replication, Actor, and Utilities groups shouldn’t be there.) Why did this happen?
