I just spotted your post and wanted to find out if you still require help, as it has been a while since this was last reported, and sadly, I haven't been able to replicate this issue.
Please look in your "Your Stuff" folder to see if the missing files can be located there or in your CC Library.
Please let me know how things are going, as I'm here to support you in any way I can, and looking forward to hearing from you.
