Curtain reinforcement problem

Friends, I have a question about curtain reinforcements in a 2 storey rigid basement + 7 storey building (floor Z4 D). A curtain with dimensions of 25x240 cm in the basement floors (head zones 50 cm each, middle zone 140 cm) decreases to 25x200 cm on the ground floor (head zones 50 cm, middle zone 100 cm). As a result of the reinforced concrete analysis, when I examine the reinforcements related to this curtain, on the ground floor (shop floor - floor height is higher than other floors), 15 Ø 14 on the left, Ø14/6 in the middle, 15Ø14 on the right, on the basement floors; left 11Ø14, middle Ø14/13, right 11Ø14. As can be seen, the reinforcements coming from below are less in the basement floors than in the ground floor. In this case, should we change the largest number of reinforcements by fixing them on the lower floors, as we did with the columns? This is related to the fact that the basement floors are rigid and the forces acting on these curtains are less than the forces on the same curtain on the ground floor. The project is in the municipality and I just realized this situation about curtains. I wanted to ask here if I should change it. I will be glad if you reply urgently.
 
At the same time, in the link you gave as a construction site; The statement "normally no adjustment is required if more reinforcement comes out upstairs" doesn't make any sense. In other words, can the normal force on a column on the 3rd floor be more than the normal force on the same element on the 1st floor?
 
The solution to the problem is already in this sentence. Since the normal force is low, the vertical element is already under the influence of the moment. The increase in the vertical reinforcement of the column in the upper floors may be caused by the difference in the Moment/Normal Force ratio.
 
Knowledge must always prevail over ignorance and prejudice. For this, I think that everyone should do their part without hesitation. Like an ant "even though it is very difficult to reach the final goal, can't we at least die on the way"
