Getting started digi xbee mesh - "MY Addres" not showing in XCTU?

Trying to setup a transmit receive example with digi xbee mesh and in XCTU, there is no MY setting showing?
I am running digi xbee mesh 2.4, firmware v 3012

What am I missing?

Is this automatically using the address on the back of the module and can’t be set?

You are not missing anything. Digi Mesh uses a 64 bit address function only which uses the SL/SH values as the source address. The MY function is a 16 bit address function that does not exists on Digi mesh.
