How to reproduce

1. change profile to 0.12mm Fine
2. enable tree support auto
3. turn off independent support layer height
4. set top z distance to 0.12
5. bottom z distance set to 0.2
6. slice
7. observe 2 layers between support interface and model (should be only 1 layer)
8. set bottom z distance to 0.4
9. observe 3 layers between support interface and model (should be only 1 layer)
10. set bottom z distance to 0.12
11. observe 1 layer between support interface and model (correct)

Actual results

the top z distance of the support interface in the sliced model changes depending on the bottom z distance set. making top z distance unreliable

Expected results

top z distance and bottom z distance should be able to be set independently without affecting the other.
