Is maybe related to T24423: New segmentation shows previous interpolation

Steps to reproduce:

• create a segmentation "one"
• segment something with 3D interpolation enabled
• create a new segmentation "two"
• uncheck segmentation "one" node in DataManager
• press "Reinit Interpolation"
• press "Confirm" in Interpolation box

result:

• interpolation of segmentation "one" is written in segmentation "two"

expected result:

• nothing is written in segmentation "two" as nothing was segmented

Tested on Windows 10.
