The attached images show Japanese and English cases.

The second item is ID 40018.

source string: - Enable Steam Overlay in Steam > Settings > In-Game tab, then restart VRChat.

Japanese translation: - Steam の設定の 「ゲーム中」タブで「ゲーム中にSteam オーバーレイを有効にする」を有効にし、VRChat を再起動してください。

It does line wrapping, but it doesn't show some part at the end of line : "する」を有効にし、VRChat"

Also, it overlaps with the next item. It doesn't show the 3rd and 4th items completely either.

The text field width must be wider than the MM width. And it should be properly laid out with the actual height.
