Exploded view problem in an SW2021 drawing

Hello 

I am currently making all the exploded parts of a machine that I designed, this machine contains several levels of sub-assemblies. After creating the BOM in the Drawing, I wanted to put the bubbles on each of the components, however on some components, I can't select them . This mainly concerns the subassembly components.

Could you help me?

 

A small clarification, these components are selectable in the other non-exploded views.

You have probably selected a type of BOM that does not allow you to display the numbering of each part but just a bubble for sub-assembly.

Below are the different types of nomenclatures:

Change the type of BOM and it should be better.

No I have already tried, the problem persists. This does not only apply to the bubbling but also, for example, to the addition of ribs.
