Inquiry regarding missing 'Unknown' (Class 0) labels in the updated DALES dataset

Our team is currently training a semantic segmentation machine learning model using the DALES-2 dataset and we have identified an issue regarding the absence of the 'Unknown' (Class 0) label in the new version.
In our preprocessing pipeline, we utilize these points to maintain spatial continuity and calculate geometric features for the surrounding local neighborhoods. Their removal disrupts the local geometry, leading to inaccuracies in feature calculation near areas previously labeled as 'Unknown'.
Could you confirm if it is possible to include these Class 0 points in the new dataset, or if there is a recommended alternative for maintaining spatial context during feature extraction?
