Hello Monika,
Please check Using Folders in PI 7.1 which mentions one of the use of folders as "Need to control authorization to specific objects. By using Folders, we can easily control access to view and change the design objects based on groups assigned to userids.".
With this point in mind, please check the authorizations associated. This may be a reason why the objects outside of the folder are being shown in the SPROXY but not the ones from folders.
Regards,
Ankit
