The Stack Blocks - Obsolete Bin Name Table tab lists the attributes referring to obsolete bin name tables (Row Table 20, Row Table 40, and Tier Table). You can edit the respective stack blocks to have them reference active bin name tables.
When you update any of those bin name references, N4 automatically regenerates the stack and section names for that block alone according to the new naming tables.
To edit the bin name tables for a stack block:
Select a row and click .
Edit the stack block's bin name tables in the Edit Stack Block form (on page 1).
