Moved Chart Doesnt appear in selection pane

I created a chart on a sheet1 from data on sheet1
I created a VBA Event Procedure that affects that chart
I moved the chart to sheet2 using the "move chart" menu option

Here's the problem...
I moved the VBA event procedure to sheet2 and made the necessary adjustment to sheet and range references
The procedure no longer works entirely correctly because Chart5 is not a ChartObject on sheet2
I discovered that Chart5 does not appear in the Selection Pane as an object on sheet2.

Does anyone know how to make the moved chart appear as a Chart Object in the destination sheet?
Hopefully without recreating the chart as it was a PITA.

Thanks

It is not part of its own Chart sheet.
It was built as a part of sheet1 and moved to sheet2 using the "move chart" menu option.

If I build a chart embedded in a worksheet it becomes an object on that sheet
in this case it was automatically named Chart5 and was listed in the Selection Pane as Chart5.
when I moved it to sheet2 it didn't appear in the Selection pane as an object in sheet2.
