Root folder of share missing files

I’ve got a share created and there are a bunch of folders which should up fine, but the root of the share also contains individual files that are not being shown when using:

Any ideas on why? I did reboot the unit. It’s a MyCloud 2TB, V04.04.02-105


What do the missing files have in common? Do they have special characters? Do they have a particular file extension? Or are the missing files mixed/random files?

The only thing they have in common is that they are in the root directory of the share. These are PDF, powerpoint, excel type files. Normal stuff really. And these file do indeed show up when using the desktop app. But not when using the web browser. I think this is a bug in the web browser “code” which displays the folders and files.
