eCALC Discrepancies

Hello everyone!
I intend to develop a 4 motor drone and given my lack of experience I followed the guidance from many articles I read, and decided to purchase an eClac license. After testing various engines and configs I went back to one that I did earlier only to find out that the results are different from the initial ones (althought I'm using the same exact inputs). How is this possible? Is eCalc actually precise or are there known flaws?
Pics attached showing these discrepancies during both calculations.
Hints about this issue are most appreciated.
