Using NCS SDK v2.1.0
Example Project: nrf/samples/bluetooth/peripheral_power_profiling
Building the example project gives build warnings:

Could you help me understand the second warning and how to fix it.
I am new to the nRF Connect SDK so I am trying to understand how the kconfig files work and all the dependencies. It appears this build has defined the acceptable range for this value as 1...0 which is non-sensical. The acceptable range is defined in Kconfig to be 1...BT_L2CAP_TX_MTU but I don't know where this value (BT_L2CAP_TX_MTU) comes from.
