File Count is accurate but Local Files are missing.

My Question or Issue

I selected a folder on my desktop, to sync to "Local Files" on Spotify.
That desktop folder has 50,326 tracks all together, however it's inevitable that Spotify would sync *all* of them.
At the end, actually 50,047 were synced. HOWEVER. At a very rough estimate, as I scroll through, I can only access about 20,000 of these songs. Basically from the top of the alphabet until partially thru the letter "G." Even better, if I select the very last visible song - as far down as I can physically scroll - and then hit "next" it goes to the rest of my local library. I just can't see, find, or select them on my own.

Where are the rest of my files? How can I get them to show up/be accessible?
