Yes, you have 2 networks and 3 devices. Remove the "Lite (TR)" network, because RMM automatically added your "Lite" device when you add Omni DSL as a Mesh system
Explain
I think you added two networks – the Mesh system with 2 devices and 1 existing extender from your Mesh-system. 2 + 1 = 3.
RMM automatically grabbed all extenders from the Mesh-system.
