How to fix it when foreign language is requested but also renders content elements of default language

When foreign language shows also the content element of default language it means the foreign language CE is not connected tot the CE of the default language.

To fix this you have to update the database records of the foreign language. By updating the field: t3_origuid and l18n_parent TYPO3 knows the content element is related to which default language content element. We can correct this by running the following query:

# Default language content element uid is: 8266
# Foreign language content element uid's are: 8268 and 8269

To fix this update the foreign language CE's to connect to the uid of the default language CE:
UPDATE tt_content SET t3_origuid=8266, l18n_parent=8266 WHERE uid IN (8268,8269)
