Device info Coordinator

CC2652
by Texas Instruments
Firmware: Z-Stack 20221226

You are using an older Zigbee Coordinator firmware for CC2652P so recommend that you upgrade that first:

• Z-Stack-firmware/coordinator/Z-Stack_3.x.0/bin at master · Koenkk/Z-Stack-firmware · GitHub

See more info and links about Sonoff ZBDongle-P firmware in this other thread as off-topic here:

• ITead's "Sonoff Zigbee 3.0 USB Dongle Plus" (model "ZBDongle-P") based on Texas Instruments CC2652P radio SoC/MCU

The firmware version on your Zigbee Router devices looks good so no need to update those.
