These warnings are coming wireless devices. Here are two examples:

 

1) Conflict between a Macbook Air (connected to EAP_1) and an iPad (connected to EAP_2)

2) Conflict between an iPhone (connected to EAP_3) and an unknown MAC ID (suspect an iPhone) (connected to EAP_2).

 

What is interesting is that they are on different TP-Link EAPs (EAP650s). 

 

 

I tried setting my lease to 2 hours and then also to 7 days. Either option didn't seem to make an impact on the problem.

That does not make too much difference to me. These pictures are generic config. I don't find anything wrong with them.

I want to know if you simplify your network, will this error disappear? Remove other devices and keep the AP and the router, and monitor if this persists.

A diagram of your network is required.

A screenshot of your DHCP reservation page.

Does it only happen to certain devices? Or everything is randomly getting the same IP?

What's the network config like on affected devices? I want to learn about it.
