Plotted-Pivot-indicator-has-DottedLine-style-sticky

I found I hand to add WealthLab.PowerPack to get Pivots plotted. Also the name changed to Pivot, PivotR1, PivotS1 from Pivot, Pivot_R1, Pivot_S1.

For some reason my chart has dotted line for Pivot and I can't change it. The PivotR1 and PivotS1 has solid line as indicated in below code.

Do you know why I can't get rid of the dotted line for Pivot?

WL8 code - Note WealthLab.PowerPack was added.

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


         _pivotpp = new Pivot(bars);
         PlotIndicator(_pivotpp, WLColor.Black, PlotStyle.Line);

         _pivotr1 = new PivotR1(bars);
         PlotIndicator(_pivotr1, WLColor.Red, PlotStyle.Line);

         _pivots1 = new PivotS1(bars);
         PlotIndicator(_pivots1, WLColor.Green, PlotStyle.Line);
