Disappearing and reappearing folders

with the media library on i have 2 folders that go missing from gallery view but can be seen in a different view,(files)  if i turn the media library off the folders are back in gallery view, these folder contain movies only…anyone have any ideas

You are not alone, I have read other users with this issue, also, it happens to me to, there is one folder that it was full of movie, the WD TV will not see this folder, unless I turn of the media library.
