Random Debug Port

When I run a WEB Core app in debug mode and then open the browser's developer tools I can see the port that the server is using ( e.g. localhost:22992 ). Every time I start the debugger the localhost port is a different number and the number is random.
In Delphi->Tools->TMS Web Options it shows http://localhost:8000/$(ProjectName). Why isn't the debugger using this setting?

Also, This app, which uses REST to get/set data in the cloud, will be running on at least 35 different Raspberry Pis. When I look at the request data on the REST server, it lists the data as coming from localhost. I know I can dig down and see the IP address, but it would be helpful for the WebCore server on each Raspberry Pi to have a unique name. Is it possible to change the name localhost?

Are you using TMS WEB Core with debugging from the IDE enabled?
If so, it is the IDE debug server that determines the port to be used.
If not, it should leave the port to default 8000.

I cannot get Delphi to not use the IDE debugger.
What options need to be set?

These are my TMS project options:

These are my Tools->Options:

The option "Enable debugging in the IDE" should be set to true.
