Interference between Macros?

I am a newbie to this and have received really good help with two macros today. However, I prematurely logged the problem as closed.

I have a macro to insert a new line in a block of cells that appears multiple times and another macro that duplicates the block, including the insert line button. Initially it seemed to be fine but now the insert line button inserts multiple lines at the top of the sheet and it seems to be copying them from somewhere else in the sheet? I suspect that I have done something stupid in not separating the two pieces of code in the macro editor properly? I also get a strange message saying "The picture is too large and will be truncated" - picture? What picture?

File attached and I have shown the code below, thanks in advance!

    Selection.EntireRow.Insert , CopyOrigin:=xlFormatFromLeftOrAbove
    ActiveCell.Offset(-3, 10).Range("A1:C3").Select
    Selection.AutoFill Destination:=ActiveCell.Range("A1:C6"), Type:= _
        xlFillDefault
    ActiveCell.Range("A1:C6").Select

    ActiveCell.Range("A1:A2").Select

    rngTo.FormulaR1C1 = "=R[-1]C[13]+1"
'    Intersect(rngTo.MergeArea.EntireRow, ActiveSheet.Range("G:K")).ClearContents
