.config file not included in decompilation but .Default. used instead

The folder from which I decompiled contains a .config file, but the .config file was not included in the new project that I saved from decompiling.

   <configSections>         <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >             <section name="PhoneDialerAPI.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />         </sectionGroup>     </configSections>     <applicationSettings>         <PhoneDialerAPI.Properties.Settings>             <setting name="DbConnection" serializeAs="String">                 <value>SQLDATABASEINSTANCE::PhoneDialerAPI</value>             </setting>

So the program is using custom config section, but all of the settings seem to have been "sucked into" a Settings.cs class and Programs.cs uses ".Default." exclusively.

Snippet

[CompilerGenerated]
[GeneratedCode("Microsoft.VisualStudio.Editors.SettingsDesigner.SettingsSingleFileGenerator", "10.0.0.0")]
internal sealed class Settings : ApplicationSettingsBase
{
  private static Settings defaultInstance = (Settings) SettingsBase.Synchronized((SettingsBase) new Settings());
 
  private void SettingChangingEventHandler(object sender, SettingChangingEventArgs e)
  {
  }
 
  private void SettingsSavingEventHandler(object sender, CancelEventArgs e)
  {
  }
 
  public static Settings Default
  {
    get
    {
      return Settings.defaultInstance;
    }
  }
 
  [DebuggerNonUserCode]
  [ApplicationScopedSetting]
  [DefaultSettingValue("SOMESERVER::PhoneDialerAPI")]
  public string DbConnection
  {
    get
    {
      return (string) this[nameof (DbConnection)];
    }
  }

When I bring the .config file into the project Program.cs ignores the config file, because all settings are retrieving from ".Default":
int dbType = Settings.Default.DbType;

string dbConnection = Settings.Default.DbConnection;
string dbUser = Settings.Default.DbUser;
string dbPassword = Settings.Default.DbPassword;
string table = Settings.Default.Table;
string serviceId = Settings.Default.ServiceId;

It's pretty clear that this isn't how the program (.EXE that I decompiled) actually operates and instead retrieves settings from the .config file, not from hard-coded settings in the .cs file.

Is this a setting in dotPeek? A bug?  

I can manually edit all of this of course, but I'm wondering if there's something I could do in dotPeek to INCLUDE the .config file and generate code that will actually use the .config file.

Thanks!
