We have already answered your ticket, but just in case if you have not seen it yet:
Please take a look at your screenshot and you will see that the category names are having special characters, that is why the connection does not work.
Please make sure:
- Do not include special characters for naming the categories, video&link and Title and description.
- Do not include spaces for naming the categories, video&link and Title and description.
- Make sure to use the exact same name for all the extensions and the category widget.
