Unit Symbols - Not Consistent?

[MisterMark]

I only have Salerno 43 but I'm sure this is an issue on many other titles... but can anyone explain why some unit symbols on the map are not consistent with the unit symbol displayed in the unit box?

In the screenshot attached labeled 'Grille' we see the selected unit on the map (indicated by a pink arrow) use the 'regular' self propelled artillery nato symbol, but in the unit box the symbol is the 'heavy' self propelled artillery nato symbol.

Furthermore, the 'heavy' self propelled artillery nato symbol is represented in screenshot attachment titled 2DSymbolsMag (identified again with a pink arrow), which is from the master map symbol file in the game directory for the magnified view.   So if this symbol is available to be used, then why doesn't the game correlate and use the correct symbol for the magnified map view?  This is just one example but there are several units with this issue that I have noticed with this title.
