Can't see subfolders in Samba share

Troubleshooting
1

I have an external drive set up as a samba share on DietPi (Raspberry Pi 4) and can access it from my second Raspberry Pi. However, on the second Pi I can only see one out of 9 subfolders and one out of several hundred files in that subfolder. My SMB conf:

[PiDrive]
        comment = PiDrive Share
        path = /mnt/PiDrive
        read only = no
        browseable = yes
        valid users = dietpi
        writeable = yes
        follow symlinks = yes
max connections = 8

I’ve tried creating CIFS mount points for the subfolders on the second Pi but then get the error “Stale File Handle” when I try to LS. Any thoughts? I’m far from an expert on Samba.

I removed all my mount points again and readded them and now it works right.
