once you siwtch to luci-app-samba, what ever the gli-web page reports is irrelvent. 50-samba creates the mount point automatically under the concept of switching usb drives and having differnent partition names of which to mount to. so now you are manual mode using luci-app-samba. the only other setting I can think of is in /etc/config/glconfig and commenting-deleting samba sectiion. also, if you must create the mount directory. ie. mkdir /mnt/sda1. all this works irelevant as to what the label is called. im assuming sda1. you still need to find partition yourself ‘ls /dev/sd*’
