Backgrounds using special://

Hi all,
i am using Arctic Zephyr in Kodi 17 version 2.3.6 and currently having issues with backgrounds copying build from windows to android.
In Movies & TV tabs i have a single background picking up my background folder in userdata which using special:// works bringing it accros on any device.
the problem is with the other tabs that have multi images. they work in testing on windows but even with special://home they are not being located.
is there something im doing wrong.
thank you
