Period-parameters-for-the-KVO-indicator-are-ignored

The period parameters passed into the KVO indicator are totally ignored. I change them, but they always show "34, 55" on the Chart for the KVO indicator. What's going on? I'm running WL8 Build 39.

CODE:
using WealthLab.Backtest;
using WealthLab.Core;
using WealthLab.Indicators;

namespace WealthScript3 
{
   public class KvoTest : UserStrategyBase
   {
      public KvoTest()
      {
         period1 = AddParameter("Period1", ParameterType.Int32, 34, 2, 60);
         period2 = AddParameter("Period2", ParameterType.Int32, 55, 2, 80);
      }
      
      public override void Initialize(BarHistory bars)
      {
         ema = new EMA(bars.Close, period1.AsInt);
         kvo = new KVO(bars, period1.AsInt, period2.AsInt);
         WriteToDebugLog(period1.AsInt + "  "  + period2.AsInt);
         PlotIndicator(kvo);
         PlotIndicator(ema);
      }

      public override void Execute(BarHistory bars, int idx) { }

      Parameter period1, period2;
      IndicatorBase ema,kvo;
   }
}
