Unfortunately, being from the support team I can only comment on the PLAXIS side.
When comparing results it is important to understand the different ways each application solves the analysis. PLAXIS is a finite element model while I noticed that this is not the case for the other model you created.
Among others, it is essential for a finite element model to have proper boundary conditions, accurate soil properties of the constitutive model in use, as well as good quality generated mesh. Then, the results can be reviewed and allow for comparison with other methods.
