Fix: Handle undefined data in RegulatoryInformationDetails

The error "Cannot read properties of undefined (reading 'filter')" indicates that the `filter` method is being called on an undefined variable within the `RegulatoryInformationDetails` component. This likely occurs when data expected to be an array is not available.

To resolve this, the code will be updated to safely access and filter the data, ensuring that it handles cases where the data might be undefined or null. This will prevent the runtime error and ensure the component renders correctly.
