Why has my ZHA connected to multiple coordinators?

I have added tcp://192.168.10.153:8889 as a coordinator using ZHA. Two EZSP entities have appeared, why is this?
Prior to this, I had added tcp://192.168.10.161:8889 as a coordinator and then deleted it. Now it is appearing as the secondary coordinator.
Isn’t ZHA supposed to only be able to add one coordinator? I suspect the secondary coordinator is fake.
I have also seen in the zigbee map that a newly added device has connected to the secondary coordinator.
