TimeSeriesSynchronizer-drops-description

When I use TimeSeriesSynchronizer.Synchronize it drops the original description on the TimeSeries. Is this intentional or a bug?

CODE:
using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Indicators;
using System.Drawing;
using System.Collections.Generic;

namespace WealthScript5 
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
         TimeSeries tsSynched = TimeSeriesSynchronizer.Synchronize(bars.High, bars.Close);
         WriteToDebugLog(string.Concat("High: ", bars.High.Description));
         WriteToDebugLog(string.Concat("Synched: ", tsSynched.Description));
      }

        //execute the strategy rules here, this is executed once for each bar in the backtest history
        public override void Execute(BarHistory bars, int idx)
        {
            if (!HasOpenPosition(bars, PositionType.Long))
            {
                //code your buy conditions here
            }
            else
            {
                //code your sell conditions here
            }
        }

        //declare private variables below

    }
}
