If I save a label preset with e.g. 10 labels once, it sometimes saves -1, which means that the last added label is not saved and therefore only 9 are displayed when the preset is reopened.
Version: release 2023.12, 64-bit Windows 10.
How to reproduce:
# create a segmentation for an image
- add 9 labels
- Save the label preset under a file.
- Delete the segmentation
- Create a new segmentation
- Reload the label preset from a file
- Then the last label is missing.
