Bugfix
| Feature | Description | Edition |
| Deleting values in LCA page | Fixed an issue where deleting values on the LCA page could cause the application to freeze. | All |
| Scenario selection freeze | Fixed an issue where selecting a scenario from certain EPDs in eco-platform could freeze the dialog. | All |

| A1–A3 value calculation | Fixed an issue where A1–A3 values could be doubled in some cases from eco-platform. Calculations now correctly use aggregated values or sum A1, A2, and A3 when needed. | All |
| EPD JSON attachment display | Fixed incorrect display of EPD values in JSON attachments caused by regional decimal separator differences. | All |
| Recalculate LCA results | Disabled “Recalculate LCA results” when no estimate or library is open, preventing script errors. | All |
