I want to restore Behavior Packs to previously created worlds from purchased Worlds (templates).  It is NOT acceptable that the Behavior Pack content is missing from the drop down list, in Game Settings, Behavior Packs! I purchased this content. Mojang, Microsoft, and developers MUST add the Behavior Packs to the Game Settings, Behavior Packs listing! And PROGRAM that properly, to actually work, so that consumers can restore Behavior Packs to purchased worlds!  Resource Packs do show up, usually. However, Mojang, Microsoft, and developers MUST do quality checks to ensure that BOTH Resource and Behavior Packs for purchased Worlds (Mash-ups, etc), are listed and can be RESTORED to users' previously created worlds!
