The Solution

The issue can be fixed inin /WEB-INF/bundles/jasperserver_messages_es.properties file by deleting the following line: 

jasper.report.view.data.snapshot.message=Donnu00e9es actualisu00e9es le {0,date} u00e0 {0,time}

and replacing it with this 

jasper.report.view.data.snapshot.message=Donnu00e9es actualisu00e9es le {0} u00e0 {1}

Then save the file and restart the server.
