When Urmila must climb 12 flights of stairs she is wearing peep-toe sandals with a heel of about 1 inch. But when she enters the flat she is wearing a three-inch heel with straps around the ankle. Similarly, when Rehka first meets Ajay Devgan she is wearing heels. When we see her entering the apartment building she is wearing flat sandals, but once inside the apartment she is wearing another - different - pair of heels.
In the beach scene just before Swati sees Manjeet people in the background are can seen rushing as if they were asked/instructed to clear the area.
