That’s a retroarch bug/quirk.  
It won’t read shader presets or shaders if the `/shaders` folder isn’t inside a retroarch folder.  
You can create a `/retroarch/shaders` folder and move your shaders there, then it should work.

A more clean approach is creating archives to install the shaders and overlays in the internal retroarch directory.

Just get your `/shaders` folder(needs to be named `shaders`) and zip it to `shaders.zip`, the same for `/overlays` to a zip file named `overlays.zip`. Then rename the extension from `.zip` to `.muxzip`.

Then grab your your newly created muxzip archives, move them to the `ARCHIVE` folder, either on the root of sd1 or sd2, it does not matter which, and then in muOS go to applications\>archive manager and install both archives.

Now those shader presets and overlays will be available within the regular retroarch overlays and shaders folders.
