Export from Layout to .dwg No.II

While exporting from Layout to dwg, bearing in mind to change to Vektor-Mode and refresh the viewport and to save…I have the following issue:

  • In the export-dwg-dialog i unchecked the Layer-Option “export unvisible Layers” but even thow one unvisible Layer is exported to .dwg… Could it be because in this particular Layer there is an external reference (a csv.-file as table)…should not be…Most of the layers i turned of are not beeing exportet correctly, as I wanted to, but this one not…Mmmh. Even when I lock and hide the layer it is exported too and visible in the .dwg- Viewer-program…
    I would be happy if you could give me a hint
