2d Contour First path too deep

[msonst]

When I'm creating a 2d Contour, the first pass is always deeper then  the stepdown.

This caused several broken parts already until I figured this out.

It seems not to be a postprocessor issue as the simulation also shows a deeper step.

Could you please let me know, what causes this?

Thanks Michael

At a guess, try turning on "Use Even Stepdowns":
