When exporting data from an issue or having an issue on the Jira Issues macro, the Assets custom field shows the object's label and key. The screenshot below shows how an object is shown on the custom field in the Jira Issues macro. The parts highlighted in blue are the object keys.

Impact

In some use cases, the object key is not needed to be shown at all as it can cause confusion to users

Suggestion

Allow to remove the object key from the export options and on the Jira Issues macro
