Samba Client creates owner of share as dietpi and not root

Interesting, I have two installs of v6.16…both are mounted to an external drive via samba-client

One shows owner as ROOT the other shows owner as DIETPI

How and why would or could samba-client create a share with Dietpi as the owner??

strange behavior

freshly installed v6.16 with samba-client creating directory under dietpi user
