Display issue of netcdf4 in GM 20.1.2

Hi,
 I have a problem with the display of gmt netcdf produced with version 6.2 in format CF1.7 (IO_NC4_CHUNK_SIZE auto, IO_NC4_DEFLATION_LEVEL 0), it's nf, netcdf 4 in global mapper v20.1.2. The points without value (Nodata, NaN) are displayed in black whereas previously the
nodata values wasn't displayed. I tried :
-> to change the parameter of gmtCOLOR_NAN (which changed from 127.5 to 128) but that didn't change anything.
-> By trying to pick the color to make it transparent, it also removes all shading.

Any idea to solve the problem ?
Thanks
Laure

    Hello,

    I suggest that you download the latest version of Global Mapper and set up a trial license to see if your file can be loaded successfully. If you are still having a problem, please contact Blue Marble Support directly via email (geohelp@bluemarblegeo.com) so they take a look. Be sure to include the netcdf file that you are trying to load. Thanks.

    Cheers,
    Bob
