Synology Drive client not syncing files from Win 10 client to Drive Server

[MikeLeone]

Using Drive Client 3.4.0 on Win 10. By default, it seems like the client is copying my entire home profile to the Drive server. Great, that's what I want. But what's happening is that sub-folders that exist on C: are created on the server (but not all), and any folders that are created are empty. No files are copied.

Here's the thing - I also use MS OneDrive. And apparently OneDrive changes the home profile to point to itself?

C:\Users\turgo\Documents>dir
Volume in drive C is OS
Volume Serial Number is 08D9-26E8

Directory of C:\Users\turgo\Documents

10/26/2023 04:22 PM <DIR> .
10/26/2023 04:22 PM <DIR> ..
09/07/2020 01:28 PM <JUNCTION> My Pictures [C:\Users\turgo\Pictures]
0 File(s) 0 bytes
3 Dir(s) 172,305,047,552 bytes free

Using the GUI, the below is what I see when I click on the "Documents" folder (I guess it's really a library?)

C:\Users\turgo\OneDrive\Documents>dir
Volume in drive C is OS
Volume Serial Number is 08D9-26E8

and so on.

So in order to use Synology Drive, and OneDrive at the same time, what should I be setting the Drive Client to copy? Using the GUI, I choose "Documents", and I end up with no files. So I instead be choosing the "C:\Users\turgo\OneDrive\Documents"??

Am I the only one having this issue? Is there something basic I am mis-understanding?

Thanks for any clues.
