Sorry, there’s a bug in the VLAN display for the XR10. When you configure the ports LAN-X1-LAN, the page displays LAN-Guest-LAN. But actually port 2 is assigned to X1, despite Guest being displayed.
If you connect a device to port 2, on the Status page you’ll see that it is connected to the X1 VLAN.
The bug will be fixed in the next update.
