Jumbled up display among multiple sheets

  I have multiple sheets in my excel . First one is input_data sheet . Based on parameters changed in input_data , cells in other sheets gets calculated using some formula. My problem is , when I change parameter in input_data , the related cells from other sheets ( where the output is based on input_data parameter) shows up overlapping with input sheet . The whole screen shows jumbled up by mixing some cells from input sheet and some from other target sheets .  I have to move between sheets to get a clear view again .

   Any idea how I can fix it ?

Thanks,
