Line and Stacked Column Chart - Display Total with quarter series

I'm struggle with getting this to work as I hope and am wondering if someone can provide a littel insight.

I have the following Line and Stacked Column Chart

The issue is when I add Total Sales YTD to the Line Values the line isn't drawn showing the total sales per year: (stays the same as above)

But if I remove the Quarter column series than it works as expected although not what I'm after:

I am trying to show sales per quarter per year, with the line showing the total sales per year. I thought I could use the same measure but perhaps not?  The measure is defined as:

Total Sales YTD = SUMX('Table1', 'Table1'[Unit Price]* 'Table1'[Quantity])

Any suggestions?
