It's August 2019 and this is still an issue.

I used the workaround, and it still exports without any of the numbers populating the cells.

I made it work this way: In Excel, when the report is launched, I clicked on to make the document editable. Only then did all the numbers become visible. I then saved to write over the blank non-editable version. 

How is this not fixed yet? At first glance, it looks like the whole thing isn't working, when in fact it is; it's just not visible.
