I cant see files under NFS usage, why?

I installed & confiugred NFS on ubnutu 18.04.

Directory /mnt/samba is shared by SAMBA and NFS server.
I'm connecting as a client by Windows 10 on it and:
- I can see/read/write directories & files on samba usages
- I can see directories by NFS usage but I can't see any files inside

What is wrong?

Files /mnt/samba on Linux ext4 partition are:
- directories nobody:nogroup 0777
- files 0777 (.exe files) or 0666 (all others)

Samba usage is configured by /etc/samba/smb.conf as:
Code:[3.TB.partition.1]
comment = 3 TB p.1 encrypted partition
path = /mnt/samba/3.TB/partition.1
writable = yes
; browsable = yes
guest ok = yes
create mask = 0777
directory mode = 0777NFS usage is:
/etc/exports:
Code:/mnt/samba 192.168.0.0/24(rw,async,no_subtree_check,root_squash)
