Surface Template material classification

I applied to a terrain model (feature definition sets volume option as:substratum) surface templaters limited with boundries. Feature Definition for templates's components have volume option set to substratum as well.

However, when calculating eatrhworks from cross-sections, surface templates are listed as design surface type in the General Leaf.

Hence I have to change component classification for these components for unsuitable.

Unfortunately cut volume is not reduced by unsuitable material removal. Neither in report nor on cross-section cut area shapes. In fill these removal volumes are not added to fill volume.

Any ideas? I am looking for a way to obsolate unsuitable material by feature option from Inroads SS2 release to include existing pavement, weak ground and topsoil removals. Using unsuitable material by station is not an option.
