Dragging from the browser respects the drop location and will insert clips contiguously on lanes. If you drop on a lane that has data it will autocrop it like this. If you drag to to the main comp track it will drop starting from the first lane and crop any data that lives there. This is by design. If you want to insert new lanes just drop to the last lane or insert a new lane and drop there. EXAMPLE: Dragging MIDI and audio clips from Browser to add take lanes EDIT: I see you mentioned
