Signals Notebook: HELM Curation is recognizing compounds with different enhaced stereochemistry as duplicates

When importing or creating monomers with the same structure but with different stereochemical configurations using enhanced stereochemistry notation, the application will identify them as duplicate structures:
- Monomers with different stereochemistry (such as R/S configurations, racemic mixtures, or specific stereoisomers) are flagged as duplicates during import or creation
- The system does not distinguish between different enhanced stereochemistry notations (ABS, AND, OR) during duplicate checking

Solution: This is an application limitation as a workaround use the manual option "Create New Monomer" in the duplicate warning window to add the the monomer to the library with a different name and shortcode.
