Volume not showing negative values in 3.0.0? #376

Hi, I am having some problems getting the volume command to show negative map values in 3.0.0. E.g. when running an APBS calculation via the plugin and visualizing the volume with the 'esp' preset, I get the following results:

Left with 3.0.0, right with 2.5.2. I also observed this with other .dx maps, where the values in the map seem to be interpreted differently by the volume representation and negative values are not at all visualized.
