I can't find these widgets in String translation or anywhere else. They are used in the Footer Content Block. All the other text blocks and contents in the Footer Content Block is translated, but not these widgets.
Welcome to the WPML support forum. Your debug info seems incomplete so I'm not completely sure what is your configuration here.
Here are few things you can review:
1. If the strings are not available in "WPML > String Translation", scroll down at the bottom left of the page and click on "Translate texts in admin screens".
- On the next page, search again the string
- Select it (checkbox on the left)
- Click on "Add to String Translation".
- Go back to String Translation to translate it
2. It seems that you're using a page builder of some sort
- Make sure that you translate your footer template in "WPML > Translation Management"
