Segments to label maps number

I am a little bit confused about how labelmap indices are determined after the segmentation->Label map conversions. I was under the impression that it was the order of the segments. Am I mistaken? Because in the screenshot below for both converted volumes the skull segment is the first in the segmentation, but it got index number of 1 in the one labelmap and the 2 in the other.

I am using the right-click convert visible Segments to labelmaps option in the data module. Is there another way to make sure label indices match the order.

Due to strong demand, we implemented preservation of label values during labelmap->segmentation->labelmap roundtrip. This is achieved by matching segment names to color names in the color table.

If you don’t want to use this color mapping then disable “Use color table values” in Segmentations / Export / Advanced.
