Attach balloon to part in assembly exploded view?

I would like to attach balloon to each part in an exploded view while the balloons show the item number of a “indented-detailed numbering” BOM.
Right now I only can get them to show the sub-assembly number.

If you right-click your view and select properties, can you verify that the “Linked to BOM” box is checked?

Edit: Is the BOM they are linked to also set to show indented detail numbering?

That’s it!
It was linked to a BOM that is on another page!
