Expansions not showing in Sounds Browser

I have an MPC Key 37 with firmware 3.4.3. I'm currently going through the MPC Bible 3 and am on Page 150. I have all the MPC Bible 3 files on a UBS storage device connected to the Key 37.

In the Sounds screen, I'm not seeing any of the expansions like is shown on page 150. I only see "Factory Expansion", like is shown on page 151 and no "User Expansions". Also, when I go to the Browser and tap on Expansions, on the left side (as shown on page 153), I don't see any of the expansion icons aside from the two Factory ones "MPC Demos & Templates" and "MPC Factory Content".

Additionally, the audio previews don't work as discussed on page 155.

I probably have a dozen expansions on that USB. Should they be showing up in the Sounds screen or on that Browser tab? I can search for these expansions and open them by navigating through folders in the browser but it would be a lot better if these could be easy shown in the Sounds page or as Icons in the Browser under the Expansions tab. Am I doing something wrong with where these expansions are placed in my USB drive? They are 3-4 layers deep on the drive.

It's been years since I've had an MPC. Any help would be great.

Thanks

MPC Expansions must be placed inside the “Expansions” folder located at the root of the drive.
