Unreal packages everything in your project not only what you use. Try duplicating your project before exporting and delete what you don’t need.

It only packages assets referenced by your maps, but you might be including maps that you do not need.

see: Packaging specific maps within a project - World Creation - Epic Developer Community Forums
