Description
When building geometry, all estimators worked fine when there are just three layers but gave all-zero results when I inserted the fourth layer.

estimators are placed between TA3 and VA2 when there are only three layers and TA and VA3 when there are four. theoretically, I literally introduced zero change to the materials in my system, so no drastic change should occur, and back-scattering particles should be detected in both cases. Yet it only functioned in the three-layer case but not in the four-layer case.
It would be sincerely helpful to solve this problem since I need to raise the height of my estimator.
