aeon nox cannot write path to background

I can select the background in the skin but Aeon nox fails to write to a folder.
I am seeing special://home/userdata/My media folder/chosen background

error is “Unable to save menu”

I believe the path should also include “profile” to write to the userdata folder.

where do I make that change?

I’ve tried convert physical paths to special but no luck.
It seems kodi 17 has changed but the convert programs are missing something.

Thanks in advance for any help
