Unfold from bus in sub-sheets broken?

Just updated to Version 9.0.0.

I’m having an issue unfolding elements from a bus in sub-sheets in a hierarchy. If I unfold a bus element in a sub-sheet, the ‘Show netlist’ operation doesn’t show it connected to the bus. The bus elements are all there (because I can select them from the dropdown), showing that the hierarchy labels are connecting, and all the connections look good. This works fine in the main sheet, but not in sub-sheets.

Not sure what I’m doing wrong, or if this is a bug. The schematic was originally created in 8.0.3 and migrated when opened in Version 9

OK, a quick update. If I add a (duplicate) bus label in the sub-sheet, the netlist shows correctly,

This is different from 8.0.3, I’m wondering if it is intended.

Main sheet:
