pac env list-settings doesn't return correct releasewave information

We have over 50 environments, and I recently created a script to gather information on the release wave updates. While most of our environments have been updated to the 2025 Release Wave 1, a few still show as being under the 2024 Release Wave 2. Both the environment release wave status page in the admin center and the about page indicate that these environments are on the 2025 Release Wave 1. It's puzzling because the information is correct for more than half of the environments, but some are displaying incorrect update statuses.
I am in GCC.

Here is the script:

# Define types of environments to query
$envType = "Sandbox", "Production"

# Authenticate to the US Government instance
pac auth create -ci usgov

foreach ($type in $envType) {
    # Retrieve all environments for the given environment type
    $envs = pac admin list -t $type --json | ConvertFrom-Json

    foreach ($env in $envs) {
        $envName = $env.DisplayName

        # Skip if environment name suggests it's a DEV instance
        if ($envName -like "*DEV*") {
            continue
        }

        try {
            $envId = $env.EnvironmentId

            # Get the release wave settings for the environment
            $settings = pac env list-settings -env $envId --filter releasewavename
            if ($settings.Count -lt 3) {
                continue
            }

            # Parse the release wave value from the returned data
            $releaseWave = ($settings[2] -split " ")[1]

            # Create an object with the environment name and release wave
            $data = @{
                EnvironmentName = $envName
                ReleaseWave     = $releaseWave
            }

            # Append the collected data to a CSV file
            [PSCustomObject]$data | Export-Csv -Path c:\temp\env.csv -NoTypeInformation -Append
        }
        catch {
            Write-Output "An error occurred while processing the environment: $envName. Error details: $_" -ForegroundColor Red
        }
    }
}

Reproduce the PowerShell script against GCC environments and inspect the output from pac env list-settings -env <id> --filter releasewavename. Compare the returned release wave with the environment release wave status page and about page; done when the command reports the correct value for affected environments.
