Disappearing share on Windows

[goral]

Hi
I just new in FreeNAS
I made my first pool and share. On this share I copy one file and make few directory.
Everything was OK, since yesterday. Today, in my Windows I can see only this one file not directory.
But wat is more strange - on android phone, I see everything!
What happen? I restart windows, but is still just one file, I restart freeNAS - nothing.
Any help why directory disappear on windows but not on android?
Thanks.
