Background of the issue:
I am trying to translate a string which has the wrong default language set by WooCommerce. The issue can be seen on this page: hidden link
Symptoms:
When I try to change the language of the string, I get the following error message: "Sie haben Strings ausgewählt, die zu einem Paket gehören. Bitte wählen Sie alle Strings der betreffenden Pakets aus oder wählen Sie diese Strings ab."
Questions:
How can I change the language of a string that is part of a package?
Welcome to the WPML support forum. I will do my best to help you to resolve the issue.
As per the screenshot, that string is part of a string package. It will not be possible to change the language of a string that is part of a string package. So we have to change the language of a string package/domain. Please refer to this article for more details.
