When using the 2D interpolation in the Segmentation view, pressing "Confirm for single slice" does not fill the previewed interpolation of the current slice with the correct value. It always uses Label 1 (even if it has been deleted).
Steps to reproduce:
- load any image and create a segmentation
- add at least one more label
- with not the first label active, segment something in two different non-adjacent slices and turn on 2D interpolation, so there is a preview shown in the in-between slices
- click "Confirm for single slice"
-> The preview is filled out in the color of Label 1, regardless of which label is currently active
- Please describe the bug or feature request as long as necessary but as short as possible.
- What information is necessary to reproduce the bug? For example, what version of MITK do you use, what is your operating system?
- Unless you are sure about the priority, `Needs Triage` is perfectly fine.
