Lumerical version change results in output discrepancy-duplicated

  In 2021, we ran the simulations using Lumerical version 2021 on Windows and stored the results in the 'Version 2021' folder. This folder includes a Matlab code for data processing (please update the file path before running).
  
  Recently, we conducted the simulations using Lumerical version 2024 R1.2 and saved the results in the 'Version 2024 R1.2' folder. We observed an unexpected discrepancy in the results, specifically a sudden shift in the range L=1.6~1.8um in the Slot_Phase (derived from the angle of S in the Slot_Sweep.fsp sweep) and notable differences in Slot_dPhase1_cor (Lines 7 and 8) in RefractiveIndex_Slot.m.
  
  We also ran the simulations using version 2023 on Linux and encountered the same issue with this jump.
  
  All affected simulation points were completed 100% shown in the attached screenshot. Could this issue be related to changes in the initial E field during the sweep or other modifications in hidden parameters between the versions?
