Losing layers on parts in a drawing

Hello

I made a shot with different layers. And I applied these different layers to the parts of my assembly present in the drawing.

When copying the tree of assembly and drawing, I lose the application of layers on the parts. Is this normal?

Thanks in advance

For my part, I only noticed this layer loss when using the envelopes, or maybe the box (apply to all views) is not activated,!?  

I want to clarify that applying a layer to a component does not link that layer to the component, it's in the MEP only, 

That said I suspect the copy, can you describe the procedure, 

 

Apparently, renaming the files in the PDM removes the layers in the drawing. I'm going to open a ticket.

You must uncheck the option in Performance "Include Wrap mode data when recording"
