Dear all, 

When I am including a new task there is always a pop up message in Spanish which says: "Información en los Calendarios y proyectos han prevenido tu acción previa. La acción ha sido revertida" it is something like: "Information related to Calendars and projects has prevented your previous action. The action has been reverted."

Can anyone help us figuring out why this pop up appears and how to avoid its appeareance?

Thanks, 

Bea
