LDCad groups parts into single meshes (as it is optimal for model editing), so the whole part is rendered dual sided or not.
If noclip is encountered or any subpart is missing winding info the whole part will be rendered dual sided.
You can check this in the logs.
You can also force all transparent parts to always render dual sided (prefs/ldraw/two sided transparency)
But it can still look wrong resulting from the draw order as LDCad only does partlevel z-sorting for transparent parts.
LDView does polygon sorting so it usually does a better job at rendering models with lots of transparent parts.
