Resaving properties list breaks index of same-named properties.

[Tajfun403]

Some properties inside an array have exactly same name, and are distinguished by some that looks like index. Each next property have one bigger index number.
Getting and resaving this property array is clearing indexes, therefore making these properties invalid.
Comparison after, and before resaving:

Screenshot uses modded file, but same is applicable to vanilla packages.
Example of issue from vanilla game is resaving export 157 from BioA_MPDish_300.pcc.
My code (changed to fit vanilla edit; relevant pcc copy pasted to bin/debug):

ME3ExplorerMinified.DLL.Startup();
var MainFile = MEPackageHandler.OpenMEPackage("BioA_MPDish_300.pcc");
var MainExport = MainFile.getUExport(157);
var PropertiesList = MainExport.GetProperties();
MainExport.WriteProperties(PropertiesList);
MainFile.save("BioA_MPDish_300_edited.pcc");`
