R7000 - IP Address Reservation settings won't save.

[StanH]

I am using these instructions:

https://kb.netgear.com/25722/How-do-I-reserve-an-IP-address-on-my-NETGEAR-router

but I can't make the reserved IP perminent. The attached picture shows the page that I got to that I can't implement. It is at [Advanced] [Setuuup] [LAN Setup]. I am probably leaving out a step. I have reached

What steps should I perform at this point to save the reserved IP address that I have specified?

I am not sure the link to picture is working. When I click it,  it wants to save rather than open.

   Still true.  A vague description of what does _not_ happen is less
useful than a clear description of what _does_ happen.

   It's the green one that says "Apply".

   It's fine.  What your web browser does with it is an argument between
you and your web browser (about which I know nothing).

> [...] When I click it, it wants to save rather than open.

   Worst case: Save it someplace, and then open the (newly saved) file.

1 Initial conditions:
All devices blocked except T1700 and TOWER, both of those are computers. TOWER is shut down. Internet is connected through the R7000. Routerlogin.net is not accessable unless Internet is connected.

2 At [Advanced] [Setup] [LAN Setup], pushed the [Apply] button. The attachment shows the page just prior to pressing [Apply]. After apply, finished I rebooted the R7000.

3 Reconnected the network to the Internet. Login to routerlogin.net. This produced:
"Windows has dectected an IP address conflict"
In Event Viewer: [Error] "The name "SERVICCO :1d" could not be registered on the interface with IP address 192.168.1.2. The computer with the IP address 192.168.1.1 did not allow the name to be claimed by this computer."

4 In Genie network map, 192.168.1.2 is the T1700, the name of the Windows 10 computer that I am running. Apparently the R7000 router blocked the computer I used to give instructions to the router!!!

5 Startup of TOWER (00:04:5A:80:4A:2F), IP is unchanged at 192.168.1.9
