Ore veins generating too big

So I'm trying to make an ore generate in the end, and the veins are generating in huge sizes which are not desired. The first screenshot refers to a test where I set the max vein size to 3, and the second screenshot when I set it to 1.

public class ModOreGeneration {
    public static void generateOres(final BiomeLoadingEvent event){
        for(OreType ore:  OreType.values()){
            OreFeatureConfig oreFeatureConfig = new OreFeatureConfig(
                    new BlockMatchRuleTest(Blocks.END_STONE),
                    ore.getBlock().get().defaultBlockState(),
                    ore.getMaxHeight()
            );

            ConfiguredPlacement<TopSolidRangeConfig> configuredPlacement = Placement.RANGE.configured(
                    new TopSolidRangeConfig(ore.getMinHeight(),ore.getMinHeight(), ore.getMaxHeight())
            );

            ConfiguredFeature<?,?> oreFeature = registerOreFeature(ore, oreFeatureConfig,configuredPlacement);

            event.getGeneration().addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, oreFeature);
        }
    }

    private static ConfiguredFeature<?,?> registerOreFeature(OreType ore, OreFeatureConfig oreFeatureConfig, ConfiguredPlacement configuredPlacement){
        return Registry.register(WorldGenRegistries.CONFIGURED_FEATURE, ore.getBlock().get().getRegistryName(),
                Feature.ORE.configured(oreFeatureConfig).decorated(configuredPlacement).squared().count(ore.getMaxVeinSize()));
    }

}
