The issues that some datasets were not visible are fixed

The issues that some datasets were not visualized on the Dataset Page are fixed now. These datasets include:

• Pacific turtle tracks: Turtle-Safe Seas Project (Blue Ocean Institute)
  where  the gridded summary layer was not rendered (the points layer was fine).
  
• Harbour porpoises, white-beaked dolphins and minke whales in North Sea - Land surveys (Caroline Weir)
  where a misconfiguration of a supplemental layer "Land surveys point effort" caused a failure to map data.
