Soundings Numbers WAY Off

I just started using OpenCPN.

It's great except. . .

The number given for the soundings make no sense. I does not matter if the chart depth units are feet, metres, or fathoms. There seems to be no consistancy either but the numbers are often off by a factor of 10.

Am I missing something.

I'm running Version 2.1.0 Build 624a on Windows.

Sounding example

I have attached an example showing Alcatraz Island in San Francisco Bay.

Look at the sounding 204 just north of the island. An object query shows. . .

Feature Class: DEPARE

Attributes
DRVAL1 18.2(m)
DRVAL2 27.4(m)

The 234 next to it shows exactly the same thing. This is typical of every sounding.

Ah...The subscripted number is 10ths. The 204 is 20.4 meters.

FWIW...
