Hello Yves,

Not a bug.
When you import a dxf into another dxf you are appended it as block (File->import->Block)
and all imported entities maintain their properties (color, linetype, layer, etc.)

The "two layers" case are related to Blocks and Inserts, and neither is a bug.

To better understand the operation of blocks see these threads:
