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 |
| Navigation to LCA page | Fixed an issue where navigating to the LCA page did not always switch to the correct tab. | 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 |
| Closing project after copying EPD | Fixed an error that could occur when closing an active project after copying an EPD. | All |
| Copy EPD for reuse | Disabled the “Copy EPD for reuse” button when an empty line is selected to prevent invalid actions. | All |
| Lifespan / EPD Catalog / Generic GWP text fields | Fixed an issue where text fields in these areas were incorrectly editable. | All |
| “Valid to (year)” field | Fixed a formatting issue so year values now display as plain integers in the EPD editor without decimals or thousand separators. | All |
