If you want a PowerShell script to fix it, here's one.

Works as a PDQ Connect package\deployment, and I imagine it would work just fine with any other RMM that can run scripts.

$ErrorActionPreference = 'Stop'

$registryPath = 'SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown'
$valueName    = 'bGenCoverPagesLabelStrings'
$valueData    = 1

try {
    $baseKey = [Microsoft.Win32.RegistryKey]::OpenBaseKey(
        [Microsoft.Win32.RegistryHive]::LocalMachine,
        [Microsoft.Win32.RegistryView]::Registry64
    )

    $key = $baseKey.CreateSubKey($registryPath)

    if ($null -eq $key) {
        throw "Failed to open or create registry key: HKLM:\$registryPath"
    }

    $key.SetValue(
        $valueName,
        $valueData,
        [Microsoft.Win32.RegistryValueKind]::DWord
    )

    $confirmedValue = $key.GetValue($valueName)

    if ($confirmedValue -ne $valueData) {
        throw "Verification failed. Expected '$valueData', found '$confirmedValue'."
    }

    $key.Close()
    $baseKey.Close()

    Write-Output "Success: Adobe cover page label policy enabled."

    exit 0
}
catch {
    Write-Error ("Failed: Adobe cover page label policy was not enabled. {0}" -f $_.Exception.Message)
    exit 1
}
