[Resolved] Translate Attributes

Problem:
The client is trying to translate product attribute labels on their site from Greek to English using WPML. The main issue is that the attribute 'Ιπποδύναμη' (horsepower) appears correctly in Greek but does not translate to 'Horsepower' in English, despite the values being translated. Additionally, there was confusion as the attribute translation seemed to indicate English as the original language instead of Greek.
Solution:
First, we recommend following the guide to find and translate strings that do not appear on the String Translation page. You can find the guide here: https://wpml.org/documentation/getting-started-guide/string-translation/finding-strings-that-dont-appear-on-the-string-translation-page/
Next, to correct the default language of a string, please follow these steps outlined in our documentation: https://wpml.org/documentation/getting-started-guide/string-translation/how-to-change-the-source-language-of-strings/
If these solutions do not resolve your issue or seem outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket for further assistance.
