Translating Issue to "Problema" is an inaccurate description

The word "Problema" has a strong implication with a negative and specific thing. Any user using Portuguese (PT) browsing their project's side bar wonders why their project has any problems at all.

Since issues in Jira can take the form of many types of work, the work "Tarefa" would perhaps be more generic and easily associated with a wide array of processes.
