Some subtotals not showing in matrix

[krobar]

I am trying to create a basic matrix that shows the quantity of items sold in each month. For certain items, the subtotals sum normally, but for other items, the subtotals aren't showing up. Below is a screen shot of my table. If you look at April vs May, you can see in the third row, the totals show up for April, but not for May. This problem is only showing up on 2 of my subtotal rows.

The measure formula for this field is 

Pck Qty = SUM(Sales_Data[Qty])*SELECTEDVALUE('Packaging Recipe'[Units])

These are both columns in imported tables.

here is my data model

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
