AC problem

Hii. I am facing an issue with tata punch accomplished manual. When i use AC on on 0.5 or 1 with positioning on front and lower vents, it blows cold air in front vents and hot air in floor vents. I feel warm in my legs. Does anyone else face the same problem. I have to use AC on higher points to get cold air on both front and lower vents. If someone else is facing same problem please let me know.
