We noticed that the Add Files buttons in the File Flipper Web Version have 6 options enabled no matter whether you are selecting the Surface, Linework, Coordinate System or Geoid Model - this is incorrect as e.g. a Geoid Model should only show GGF files, a Coordinate System a DC or CAL file and Linework an SVL/LandXML/DSZ and a Surface a SVD/DSZ or LandXML etc.
