Hello,
Sorry for the delay.
1. The tagline is already updated:

Please clear your website cache and check again.
2. The Open External Links in the New Tab option only works for the links added in the default content editor area.
If the links are added with some plugin/theme, you need to disable it from the setting of that plugin/theme.
Hope that helps.
Thank you.
