Per-location view settings don't work at the folder level in Document Library

[YasmeenSK]

Hello, 

I'm trying to set up per-location view settings for nested folders in a Document Library. I used the following articles as a guide: 

How to create different Views for different folders

https://learn.microsoft.com/en-us/sharepoint/troubleshoot/lists-and-libraries/per-location-view-sett...

https://support.microsoft.com/en-us/office/configure-the-availability-of-views-for-a-location-in-the...

However, it's not working. The setup I'm looking for is:

Document Library

View 1 only:

→ Top Folder 1

→ Top Folder 2

→ Top Folder 3

                           View 2 only (within Folder 1):

                           ↳ Sub Folder 1a 

                           ↳ Sub Folder 1b

                           ↳ Sub Folder 1c                         

Here are links to screen captures from SharePoint.

Image 1 - Settings : Per-Location View Settings - For View 1: All Documents

Image 2 - Settings : Per-Location View Settings - For View 2: Year In Descending Order

What am I missing? 

Thanks,

Yasmeen
