Volumio 2. 632 - No files in NAS directory

On 2.632 version there is a new bug, it’s not possible to see the files uploaded on NAS directory if I use web access. Instead If I search the files with a file manager of windows or IOS I can find the files and play them perfectly.
Previous Volumio versions works correctly.
I have three raspberry B 3+ with different Dacs, one only updated to 2.632 version.
I have to update Volumio with caution after last versions with more bugs then the past.
