Problem with OSMC samba server

I have 2HDDs and one 128 GB Stick running on my Pi. I’ve installed the OSMC samba server.
On my Windows 10 desktop, I find only the 2 HDDs. No stick.
The stick is ext4 formated and mounted. I can see him over SSH. Whats going wrong? Is there a way to configure the samba server manualy?

Should be no need to configure it manually - all mounted disks should be shared by Samba automatically. Are you sure stick is mounted under /media automatically ?

Please provide debug logs, at minimum the system journal so we can see what is happening.
