Incomming call going to wrong Ext

Hi everyone, I set up an inbound call to go from queue (1) to ext(1); if queue (1) fail, call go to queue(2)

But when ext(1) answers the phone - in 1s, the call automatically goes to queue(2), and ext(2) answers the phone. As picture below.

Anyone know about this issue?

Need to look at the Asterisk CLI log to confirm why the call went to queue (2).
