Interference Dws1000 shield on Nucleo F439zi dual tag dual anchor

So have successfully got one tag and one anchor reading accurate measurements for me. I’m using the Thomas thoro 0.9 library on arduino.

I want another paired tag and anchor to read measurements too but it’s interfering with my other tag and anchor pair.

I tried
channel 5 on Tag1 Anchor1.
Channel 2 on Tag2 Anchor2.

So I noticed when I disconnect anchor 2, tag 1 and tag 2 started to serial print the identical distance.

Shouldn’t tag 2 basically shut off?

And the same is true when I unplug anchor 1, tag 1 and tag 2 prints the same distance.

I’ve tried different addresses, channels, but nothing works.

I really need help with this one. I would think this unit would have the simple feature of working with multiple uwb units?

And yes I triple checked the channels were uploaded correctly

Thank you
