Preconditions:

1. On Instance-level site settings: Control Panel > Configuration > Instance Settings > Localization > Language, there must be a minimum of three (3) languages under Current list.
2. Prepare a site in the portal instance.
3. On Site Administration (site-level) > Configuration > Settings > Languages, set settings to "Define a custom default language"

Steps to Reproduce:

1. Navigate to Control Panel > Configuration > Instance Settings > Localization > Language.
2. Move one language from the Current list to Available list.
3. Click SAVE.
4. Go to the Site Administration settings of the created site: Site Administration (site-level) > Configuration > Settings > Languages
5. Take note of the listed languages under Current list. Click SAVE. Error:Your request failed to complete. popup appears.
6. Go to Site Builder > Pages, then add a new page
7. Open Configuration for the created page and click the Language button next to any localizable field

Actual behavior:
The language removed from the instance-level settings was not removed from the site-level settings.

Expected behavior:
Once language is removed in portal level, it should be removed for all the sites as well.
