Missing files

I use Mycloud 2TB with iMAC and iPhone.
sometime I moved files to other directory by iPhone app, I couldn’t see some or all files access via Finder.
Only I can see all files with SSH and iPhone App.
Also I changed that files’ permission and owner, but I can’t solve problem.
please help me
