Hi guys,

TZ Portfolio+ is an open source portfolio extension that has reached out thousands of users all over the world. It means the extension is supposed to be stable in multiple languages, so that users are able to enjoy it not only in a standard English, but their mother language also. 

Thanks for the feedback of our client, we found a language issue in core package and decided to fix it in version 2.3.8. If you login your administrator with a language different from English, you might encounter raw language strings that haven't been translated yet. This issue can probably make you frustrated because you don't know what values they stand for.
But don't worry! TZ Portfolio+ 2.3.8 did address it. Let's update and check again.

Changelog - Version 2.3.8 

- Fix issue: language strings didn't show value for addons and styles properly in back-end.
