ZFS mountpoint not showing when selecting Media Folder

I have installed LMS in raspberry pi 4. Installation has gone well, however when trying to select the Media Folder, where my music is, I can't find it in the list. I have a zfs filesystem mounted at /tank however this is not showing in the list. I have tried mounting it at different mountpoints, however the folder disappears from the list, irrespective where I mount.

LMS view


Linux view


Any suggestion how to select the appropriate folder mounted at /tank?
