Hello There,
Thanks for contacting WPML Support. I will try my best to assist you in this matter.
I understood that somehow the language of some tags is marked incorrectly. If you haven't translated the Tags yet, you can change the language of the Tags. Please check the following steps to understand the process.
- Navigate to "Posts > Tags" from your WordPress Dashboard in the English language.
- Find the Tag and click on "Edit"
- Scroll down a bit and you'll see the Language Metabox(hidden link). Select your preferred language from there and update the changes.
In case if you can't select the language, then check if the Tag is translated already to that language under the "Translations" section. If you found that translated, then simply 'delete' the Translated Tag by switching to that language. I hope it will help.
