Some stratigraphic units were redefined by DEM recently in SA Geodata leaving them with no map_symbol set, which meant the derived aquifer code will not have a code. This progated through to the "Aquifer" value under the GetAdvancedListsData request, where most entries should (and used to) have a "V" key and "T" value. Now some, such as "Nonning Rhyodacite" are missing a "V" key, leading to this error.
This commit filters those out until the underlying data can be fixed.
