Button Text in Language Tab

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

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

Start by locating the Language tab and reviewing all button labels and language names shown there. Apply one consistent capitalization style and choose a single language-name presentation convention, then verify that every entry follows it.
