I use the TP-Link Easy Smart Configuration Utility to configure 802.1Q VLAN on my TL-SG108E Switch. As I tried to change the Standard VLAN 1 Name from "Default_VLAN" to Default I get a Message "VLAN Name should not be more than 10 Characters...". The VLAN Name Field shows a String "7_UdlWO5gM5U6CQ" but I never entered everything.

I already had reset the switch many times whitout success.

Anybody have a idea how I can change the VLAN Name and set the Port to Tagged?
