Raycast2D not detecting specific CustomDataLayer of TileMapLayer when Target_Position of ray is changed

Godot Version

4.5.1.Stable

Question

im not exactaly sure whats going on but with my raycast system, if my players sprite isn’t flipped then point the raycast to the right, and if it is flipped then face it left, pretty simple. now i have a tilemap with custom data attached to the tiles, and ive set it up properly so the raycast can detect the custom data on the tilesets, though for some reason it can only detect the data if the raycast is facing right, so when i flip my raycast to the left or facing upwards to detect the bottom the tile, it cannot detect that theres any data on the tile. why is this exactally??

Picture showing customDataLayer and how ive applied it:

Code for raycast detecting customdatalayer:

	if Input.is_action_pressed("Pec") and pec_ray.is_colliding():
		var collider := pec_ray.get_collider()
		if collider != null:
			wallPecing = true
			if collider is TileMapLayer and collider.is_in_group("Escalator"):
				onEscalator = true
				escalatorPecing = true

				var layer := collider as TileMapLayer
				var hit_pos := pec_ray.get_collision_point()
				var cell := layer.local_to_map(hit_pos)
				var tile_data := layer.get_cell_tile_data(cell)

				if tile_data:
					var dir_facing : String = tile_data.get_custom_data("DirectionFacing")
					if dir_facing == "Left":
						is_left = true
						
					if dir_facing == "Right":
						is_right = true

Code for changing raycast’s position and target position:

		## UPWARDS PECING RAYCAST FLIPPER
		if AnimSprite.flip_h == false:
			pec_ray.target_position = Vector2(0, -5)
			pec_ray.position = Vector2(2, -1)
		if AnimSprite.flip_h == true:
			pec_ray.target_position = Vector2(0, -5)
			pec_ray.position = Vector2(-2, -1)

	else: ## NORMAL LEFT/RIGHT PECING RAYCAST FLIPPER
		upPecing = false
		if AnimSprite.flip_h == false:
			pec_ray.target_position = Vector2(5, 0)
			pec_ray.position = Vector2(0, -1)
		if AnimSprite.flip_h == true:
			pec_ray.target_position = Vector2(-5, 0)
			pec_ray.position = Vector2(0, -1)
