'isEnabled' not evaluated for generated symbols

dotnet CLI (dotnet new)

Describe The Bug

when I use 'isEnabled' in a generated symbol it does not seem to evaluate and always processes.

example:
Foo.cs

public class Foo
{
    public readonly int FooId { get; init; }
}

template.json

{
  "name": "Tests",
  "identity": "Tests",
  "shortName": "tests",
  "symbols": {
    "ChangeFoo": {
      "type": "parameter",
      "dataType": "bool",
      "isRequired": true
    },
    "IdentifierName": {
      "type": "generated",
      "generator": "constant",
      "parameters": {
        "value": "Bar"
      },
      "isEnabled": "ChangeFoo",
      "replaces": "Foo",
      "fileRename": "Foo"
    }
  }
}

When executing dotnet new tests --ChangeFoo false, I expect it to generate 'Foo.cs' as is.
Instead, it generates 'Bar.cs' with all Foo replaced to 'Bar', which I expect to happen when I execute dotnet new tests --ChangeFoo true instead.

It seems to correctly evaluate if I change 'IdentifierName' to 'parameter' without changing the 'isEnabled' condition

"IdentifierName": {
      "type": "parameter",
      "dataType": "string",
      "isEnabled": "ChangeFoo",
      "replaces": "Foo",
      "fileRename": "Foo"
    }

Calling `dotnet new tests --ChangeFoo false --IdentifierName Bar' will not replace 'Foo' as expected

To Reproduce

Steps:

1. create (and install) basic template setup with .template.config\template.json and Foo.cs as described
   .
   ├── .template.config
   │   └── template.json
   └── Foo.cs

2. run dotnet new tests --ChangeFoo false

3. check generated file
