Flexible load of layers

hello I’ve been seeing how to do it with Sample Selector template (as Hot Brass)
I first created a working directory with Export Program as VST3 Preset with Files …
I have saved it in c: / documents / my library
and a vstpreset and a folder called Mother Source have been generated with the samples and macropages, I have added a folder called Layer Presets and added a few preset of my layers.
and I have loaded the vstpreset again to create the relative paths that I think are needed and I have configured the Sample Selector template as you see in the photo, but it doesn’t find anything …
something escapes me?
I tried to find the Hot Brass folder to see what the structure is like but it has been impossible for me to find it.
any advice?
