Thanks for the clarification. I have done some research and think this is related to the two versions of Portuguese available on Windows:
- Portuguese (Brazil)
- Portuguese (Portugal)
Which language do u have installed on the client? (I am guessing u have Brazil) In parallel I have reached out R&D team to clarify. In addition, there is a capability to be added in next Client release - E88.40 - called "Aggregation of locales in the UI" where The UI will be displayed in a language, no matter the locale origin and see there is some discussion there about Brazil. As mentioned will try and get more details on the specifics
As always, opening a TAC case will also get you any necessary support
