That shouldn't be necessary. It isn't a matter of something being done wrong that prevents it from loading, but that the mods don't have anything to be told to load.
For example, UEF ships in Blue Planet are shown on the radar as dots, but most GTVA ships have icons. It's loading that table from MV_RadarIcons.vp in the MediaVPs 2014 folder. Let's say it's overwritten by adding a new radar-shp.tbm to Blue Planet's Data/Tables folder.
Those two Sathanas icons are actually Narayanas, because I made the table telling it to do this:
#Ship Classes
;;UEF
$Name: UEFg Narayana
+nocreate
$Radar Image 2D: radar-sathanas
#End
With a proper list containing the rest of the species references and ship classes you'd then eventually have radar icons for all ships.
