Select mode: Export to CellDesigner does not work

When selecting an area in the map (tested for: https://minerva-dev.lcsb.uni.lu/minerva/index.xhtml?id=app_model#)

After Export as map > CellDesigner SBML, I get the following error: {"error" : "Internal server error.","reason":"First and last point in the line must differ but found: Point2D.Double[70110.33901292634, 13323.311754365954], Point2D.Double[70110.33901292634, 13323.311754365954]"}
