There are lead styles that need to be clicked twice, the first time to determine where the arrow is pointing and the second time to determine where the symbol is placed.
The leadless style only needs to be clicked once when labeled on the edge line to determine the position of the symbol. When marking the size boundary line, you need to click twice, the first time to determine the position of the symbol and the second time to determine the direction of the symbol.
