I have a backup share with a number of folders under UnRaid 6.11.5. Most folders in the share seem to work as expected but I found one folder (my Image folder) that when I look at the content using the UnRAID terminal or by navigating to the share content using the UnRAID web console contain 192 subfolders but when viewed from Windows 10 only show 7 folders and the content of these folders are not even correct (one folder does for instance seem empty from Windows but contains a number of files on the UnRAID system).

I have not changed any SMB parameters (just enabled sharing) and I have tried setting all permissions and ownerships for the share to the default using the "New Permissions" tool. The share uses caching Yes.
The only unusual thing I can think of is that I have some folder names with space and international characters but it is not consistent that these are the folders that are missing and other folders that also contain this kind of names do work as expected....
I can also mention that I have now tried mounting the share with NFS and then all the directories and files are present and that I tried the SMB share on another computer and it shows the exact same wrong content so it does not seem to be a problem with the client computer.

 

Edit: I received help by UnRAID support - after disabling "Settings->SMB Settings->Enhanced macOS interoperability:" the problem disappeared and all files now seem to show up,
