Incorrect Graph display to Grid layout

Hi Gurus,

I have a 2x2 grid which displays 1 or more KPI graphs up to 4.

I am having an issue where when I make a KPI select of 4 KPIs my display is good,

however when I change my selection to 1 KPI the remaining first grid is correct

but the remaining 3 grids display previous graphs.

I am setting initial KPIs using KPI Dimension Filter_0

Making second KPI Selection using KPI Dimension Filter_1

Why am I not getting just the one chart when I select 1 KPI?

Good display,

Should not have but the first graph displayed.

Script is long that is why I hesitate to copy.  Is there a way to clear the three incorrect Bar charts.
