Only some files on local network shares (SMB) are visible

I am using VLC Android from the f-Droid store. On my laptop running on Ubuntu 18.04, I share some media files through Samba. It is configured so that no authentication is needed. VLC can see only some of the files and folders listed. Other applications on my android like Ghost commander can see all the files. When I move the files around into different folders, some of them appear but not all of them. Also, my computer appears twice in the list of computers on my local network but I guess that is a separate issue. The list of the files that are visible and that are omitted seems to be stable, but when I remove some of the files, they also disappear from view in VLC.
