we had a issue where we used the zdo_mgmt_lqi to find what the network looked like. and we have found somthing we belive is a bug. i have replicated the issu with the zigbee light bulb exsample. if the chip is setup to be a end device, and have router inbetween in and the cordinator asking the mgmt_lqi_req the neighbor table most likly will have multible entry withe the releationship parent. my understaning is that only one entry should be parent?
this was tested on nrf connect sdk 2.9.1.
