Instead, it breaks down the kit and considers the components individually.\n\nIn the platform Logistics Shipping Simulator, KIT SKUs returns SLA normally, but the metadata fields `Zip code range` and `Weight range` appear empty.\nThis only happens for KITs, but works normally with single SKUs.\n\n## Simulation\n\nPrerequisites: A VTEX account with Logistics configured and at least one KIT SKU, with components properly configured and freight table populated.\n\nSteps:\n\n- Open the Shipping Simulation in Admin via Logistics > Shipping Simulator.\n- Simulate using a KIT SKU and a zip code\n- Observe that SLA options are returned, but the “Zip code range” and “Weight range” fields are empty in the result panel:\n ![](https://vtexhelp.zendesk.com/attachments/token/CvTMgIytcecA07TOkM22vBcDq/?name=image.png)\n\n\n- The same appears on Devetools debug:\n ![](https://vtexhelp.zendesk.com/attachments/token/rxmxeFqsTvUJ9GzXH17QNd1KZ/?name=image.png)\n\n\n- Compare by simulating a non-KIT SKU and note that the fields populate as expected for simple SKUs.\n\n ![](https://vtexhelp.zendesk.com/attachments/token/VlnVeTUDJvtU8zEBBjFlh9iLv/?name=image.png)\n\n## Workaround\n\nThere is no workaround, since **there is no operational impact to checkout or SLA calculation was identified.**\nThe issue affects simulation display only, but the calculation is correct and purchases are not affected."}
