Plays the only ONE song

I have installed the application on Samsung S 3 mini. It detects my Synology DS110j and shows the Audio, Photo & Video data according to the settings in the DS. After selecting e.g. a CD folder it shows all songs.
The problem is that it only plays the only ONE song selected. When I activate the “arrow circle” button in the renderer (right button) it does not play the next song of the CD-Folder, but a song from the “recently played” (local?) folder.
A similar situation I see, when selection a photo- folder. It also shows one picture only.
What can I do to persuade the app. to play the entire content of a selected folder or song list?

AMENDMENT:
The app is the Ginko DLNA Player
