I get the correct mass in segment 1 cswp practice exam, while I cannot get the correct mass for question 2

Hello,

 I can build the part with those three sets of numbers originally and I can get the correct mass for each set of global variables. However, I cannot change the equation numbers for one part, as long as I change the global variables, even though I change it back, the mass will lose about 200 grams. Attached are those three parts with correct mass based on those three sets of numbers. And the pictures with I update the variables to question2 then I get the wrong mass:16407 instead the correct 16490.45. I struggled in this for 3 days and I rebuild this again and again. It 's awful that I still cannot solve this problem. If anyone can help me to check my parts. I will really appreciate! Thank you so much!
