Base path is not concatenating with operation path

I am trying to model couple of API’s in one OpenAPI 3.0 yaml file using stoplight editor on local machine 1.12 version. The issue I am facing is operation path is not concatenated when I try to mock the API.

servers:

  • url: ‘{protocal}://{environment}:{port}/customer-management/v{version}’
    variables:
    environment:
    default: localhost
    enum:
    - test.com
    - localhost
    protocal:
    enum:
    - http
    - https
    default: http
    port:
    default: ‘8080’
    version:
    default: ‘1.0’

paths:
/customer:
post:

In the above I expect URL to be formed in mock is http://localhost:8080/customer-management/customer, but in the mock operation URL is coming as http://localhost:8080/customer

So mock server is not concatenating base path defined in servers section with operation path. Is this known issue, any alternative or fix for this ?
