Matrix not expanding down all levels / missing row?

[AC23VM]

Hi there.  Hopefully a quick question.  I made 2 almost identical matrices.  Each has 3 rows, with the first row different across matrices - let's say the first matrix has rows A, B, C, and the second matrix on a different page has D, B, C.  When published to the workspace, matrix 1 displays all rows in tiers, A > B > C.  However, matrix 2 seems only to display 2 rows, D > B.  I've expanded down with the dual arrow button, but it seems like it's publishing as if C isn't there.  I've taken C off in Desktop, re-added and r-re-published, but again it's not there.  Bit confused since the first matrix is exactly the same build and works fine.  Anyone know what's going on?

I wonder if it's a bug.  I've just copied the matrix onto a new page and re-published, and it works perfectly on that new page.  Exact same filters, nothing added, nothing removed.

@AC23VM That's strange, but good to know that it's working for you after creating a new page.

If you find this insightful, please provide a Kudo and accept this as a solution.

Thank You!

Check Data Availability for Row C

1. Verify whether C has data for the filters applied to the second matrix.
2. If C has no data for the current filter context (e.g., page filters, report-level filters, slicers, etc.), Power BI will not display that row.

I don't think there are any filters on.  It displays fine in Desktop, but disappears when published, no more filters are being added.

@AC23VM Can you check if the C category has any data available under the D and B hierarchy? 
Also, try enabling show items with no data from the visualisation pane for the row C:

Yes, it has data available.  As I say, it's displaying perfectly in the Desktop.  It's like that row disappears when published.  There are 4 visuals on the page - the other 3 remain identical between Desktop and Workspace.  It's just that matrix that changes.  And again, there's an almost exact copy on another page which isn't changing when published.
