Neoload GET action URL has port number

Howdy!
I'm new to Neoload and am working to learn it so that I can recreate a lot of Postman microservice API tests into it for CI/CD and overnight batch testing.
.
.
The requests I'm beginning with are pretty simple, they have a hostname, directory path, service name, and endpoint.
Such as:
https://servername.com/api/folder/scheduler/whoami
.
However, when I build a Server definition and refer to it within a UserPath-Action, the request always ends up looking like this: https://servername.com:NNNN/api/folder/scheduler/whoami
.
where :NNNN is the port number as defined in the Server definition.
(The Server definition screen will not allow me to remove the port number.)
.
Testing in Postman shows that any port number in the request URL breaks the request..(It's possible this is because of vTM device networking rules which handle load balancing between multiple instances of the microservice.)
.
.
How can I remove that port number from my User Path Action URL?
.
.
Thanks in advance!
