OPPID assemblies duplicate non intelliegent graphics

Hi,

We're trying create/use assemblies that have non intelligent graphics. For example, text elements. Creating the assemblies in not a problem but when inserting one is creating multiple copies (3) of all non intelligent graphics. In the picture below, text "CONCENTRATE" and material lines in blue are all inserted 3 times even if they exist only once in the assembly. Any idea how to get this right?

Best regards

Alain
