Label "GENERAL.NAVIGATION.CASES" not translated when http://localhost:8080/flowable-task/workflow/ is accessed by the first time

Hello.

I noticed that when I navigate from the http://localhost:8080/flowable-task/#/ to http://localhost:8080/flowable-task/workflow/#/tasks, both tabs "Tarefas" and "Processos" are correclty translated, but for the "Casos" tab, the localization key GENERAL.NAVIGATION.CASES is shown instead.
But then, if I click on the GENERAL.NAVIGATION.CASES tab, then the text is "Cases" is shown.

So, this is not related with the non Brazilian Portuguese translation #652 , but with the key not being replaced by the right text.

First access:

After clicking the tab link:

http://localhost:8080/flowable-task/workflow/#/tasks に初回アクセスしたときの動作を再現し、Cases タブと、クリックした後の動作を比較します。ローカライズキー GENERAL.NAVIGATION.CASES がどこで読み込まれるか、または置き換えられるかを追跡し、初回アクセス時とナビゲーション後の両方で翻訳されたラベルが表示されることを確認します。
