Button Text in Language Tab

[Margaret-Petersen]

Description
The button text in the Language tab lacks consistent capitalization. Additionally, some of the languages are displayed in their native script/style while others are in English, leading to inconsistency in presentation.

Describe the solution you'd like

1. The first letter of every word in the button text should be capitalized (e.g., "Swedish" instead of "swedish") for consistency.
2. Language names should either be uniformly displayed in their native script/style or in English, with clear guidelines applied across the tab.
