Short config section used instead of long

I created a class to store project settings, but when I attempt to read one I get the following fatal error:

Short config section used instead of long MyPlugin.MyPluginSettings

#pragma once

#include "CoreMinimal.h"
#include "MyPluginSettings.generated.h"

UCLASS(config=Engine, defaultconfig, meta=(DisplayName="My Plugin's Settings"))
class MYPLUGIN_API UMyPluginSettings : public UObject
{
	GENERATED_BODY()
	
public:
	UPROPERTY(config, EditAnywhere)
	bool bEnabled;
};
// ----------
void UMyPluginBPLibrary::ReadProperty()
{
    bool bEnabled;
    if(GConfig->GetBool(TEXT("MyPlugin.MyPluginSettings"), TEXT("bEnabled"), bEnabled, GEngineIni))
    {
        UE_LOG(LogTemp, Warning, TEXT("MyPlugin.Settings: bEnabled: %d"), bEnabled);
    }
    else
    {
        UE_LOG(LogTemp, Error, TEXT("Failed to read property"));
    }
}

If I shorten it from “MyPlugin.MyPluginSettings” to “MyPluginSettings” it does not crash, but it fails to read the propertly.

Using the long name and prefixing the section with /Script worked, but there are other plugins that only use the long name.
