Matrix Visual - Duplicate Subtotals

Hi,

I have a report with a live connection to an on-premise SSAS model.  Within the report, I've got a matrix visual to show sales by customer and by order.  The visual is set up as follows:

Row Headers

• Stepped Layout = Off
• Word wrap = On
• +/- icons = Off

Subtotals

• Row subtotal = On
• Apply to labels = On
• Row subtotal position = Top
• Per row level = On
• Customer subtotal = On (provides grand total for visual)
• Customer Num subtotal = On (provides customer total for visual)
• Doc Type subtotal = Off
• Order subtotal = Off
• Line # subtotal = On (provides order total for visual)
• ISR subtotal = Off
• Description subtotal = Off

My issue is that I am getting duplicate "Order Total" lines at the bottom of each customer group (see screenshot).  The lines at the bottom labeled "Order Total" actually display the "Customer Total".  This certainly doesn't seem like expected behavior.  Any ideas on how to resolve this?

Update 1

Upon more experimenting, this only happens when per row level subtotals are turned on and some row levels are "skipped".  For example, if I turn on Doc Type and Order level subtotals, I don't get an extra subtotal row at the bottom.  It's like Power BI is bound and determined to show the "off" subtotal somewhere.

Possible bug?

Update 2

I built a very simple model with a single static table consisting of the same fields displayed in the matrix visual.  I duplicated the visual in this test model and I get expected behavior.  No extra subtotals.  Possibly this behavior only occurs with live connections?
