Default value of properties

[celicoo]

I'm using the following model to validate the body of one of my endpoints

{
	"type": "object",
	"required": ["parsingRules"],
	"additionalProperties": false,
	"properties": {
		"parsingRules": {
			"type": "object",
			"required": ["rules"],
			"additionalProperties": false,
			"properties": {
				"delimiter": {
					"type": "object",
					"additionalProperties": false,
					"default": {},
					"properties": {
						"flags": {
							"type": "string",
							"default": "g",
							"pattern": "^(?:([gimuy])(?!.*\\1))*$"
						},
						"pattern": {
							"type": "string",
							"default": "([\\S\\s]+)",
							"format": "regex",
							"pattern": "^.{1,}?$"
						}
					}
				},
				"rules": {
					"type": "array",
					"minItems": 1,
					"items": {
						"type": "object",
						"required": ["name", "pattern"],
						"additionalProperties": false,
						"properties": {
							"name": {
								"type": "string",
								"pattern": "^.{1,}?$"
							},
							"flags": {
								"type": "string",
								"default": "",
								"pattern": "^(?:([gimuy])(?!.*\\1))*$"
							},
							"pattern": {
								"type": "string",
								"format": "regex",
								"pattern": "^.{1,}?$"
							},
							"type": {
								"type": "string",
								"default": "System.String",
								"enum": [
									"System.Boolean",
									"System.Byte",
									"System.Char",
									"System.DBNull",
									"System.DateTime",
									"System.Double",
									"System.Int16",
									"System.Int32",
									"System.Int64",
									"System.SByte",
									"System.Single",
									"System.String",
									"System.Text",
									"System.Text.StringBuilder",
									"System.UInt16",
									"System.Uint32",
									"System.Uint64",
									"Sytem.Decimal"
								]
							}
						}
					}
				}
			}
		}
	}
}

And the validator is ignoring the default properties. Is this normal?
