Lightroom Deleting My Folder Contents After Importing

In Lightroom Classic, when I click on “IMPORT,” I see ALL of my folders that I want to import. (see attached screenshot) The list of folders in Lightroom matches what I see in Windows Folder Explorer.   

So I select/click on the top-level folder, for example “2014” on the IMPORT “FROM” portion of the window to tell Lightroom where to find my import FROM folder. 

Then I click on “2014” on the IMPORT “TO” portion of my screen to tell Lightroom where to place my imported folder and files.   

Then I click on “IMPORT” at the bottom right of my screen and the IMPORT begins. 

After the import process is done ALL of my sub-folders that have an English name associated with the YYYY-MM-DD date format, for example, 2014-02-19 Tulip Garden”,  are devoid/missing my photo files. 

Why is this happening?  Thanx.
