memoQ's UI is localized into several languages such as German, Hungarian, Spanish, French, etc.
When you switch the UI from English to e.g. German, you can also use LQA models with a different UI. The available localized models can be found under Tools > Options > Default resources > LQA models. These are local models. In order to have them available in online projects, you need to publish them on your memoQ server. Go to the Resource Console > LQA settings, and select the LQA model which you wish to publish. Then click the Share on server link, and publish the LQA model (you need to have the permission to publish a resource on the server). When you now create an online project, you can add an LQA model in a different language than English.
