Tuff variants in the wrong tab in creative inventory

Tuff brick, wall, slab, stairs, and chiseled tuff appear in the "Nature" tab in creative inventory. Their stone and other block counterparts are all in the "Construction" tab.

In the "Nature" tab there is no other wall, slab or stairs, and the only other brick or chiseled blocks are the infested stone variants. Tuff variants are out of place here.

Please fix this inconsistency.
