Multi-timeframe-intraday-Point-and-Figure-streaming-charts-erroneously-intercross

I'm running WL7 Build 27 with TrendChartStyles build 4.

I open 3 charts, all with symbol SPY, and set them to streaming (IQFeed). Then I configure the 3 charts, all to point and figure with the following settings:

Chart1
Timeframe = 30min
Calculation = High Low
Box Type = Fixed
BoxSize = 1
Reversal Count = 1

Chart2
Timeframe = 5min
Calculation = High Low
Box Type = Fixed
BoxSize = 0.5
Reversal Count = 1

Chart3
Timeframe = 1min
Calculation = High Low
Box Type = Fixed
BoxSize = 0.2
Reversal Count = 1

Then I wait and when a new bar arrives and the charts redraw, then the Point and Figure BoxSize setting for a chart (sometimes 30min, sometimes 5min) changes from its original value to the value from the 1 min chart.

Then if I manually change the chart back to its proper value however then the point and figure x and o's get rendered completely incorrectly.
Do you see this issue also?
Thanks for the support
