MyVolumio can´t see all the music library on PC

I have a Pi4 and a Windows PC in my home network. Have all my music library on the PC, and the Music folder shared on the network. I want to access it with Volumio.

On Volumio it only shows some 200+ folders (up to the first folder on letter M).

On an iPhone with MConnect app I can see and play all folders. The same on an old Android tablet.

So it seems to be an issue on the Volumio side.

Any help, please? Someone with the same kind of setup that can access more than 200+ folders?
