EVB1000's (Anchor-0) LED-6 Flashes, But GUI doesn't Discover

Hello!

Anc-0 (EVB1000) LED-6 Flashes when blinks are received from Tags (0 & 1, but 2)

Tag-0 (EVB1000) ---------------------------------------GUI Discovered Tag-0
Tag-1 (DWM1000+MCU)------------------------------GUI Discovered Tag-1
Tag-2 (DW1000+MCU) New board-----------------Not Discovering Tag-2. Anchor LED indicates receive, but No GUI Display. (In Tag-2, TX, RX LEDs blinking, But SFD & Rx OK not showing up)

All firmware versions are 2.25

How to troubleshoot using DW’s test utilities? Any help highly appreciated.
Thanks in advance:hugs:
