This seems to be a recurring problem whereby the display text for various words has spaces instead of the diacritic marks. For example, "Fěnsè" is displayed as "Fe nsè" and "Kāfēisè" is displayed as "Ka fe isè". If you highlight the word to add it to vocabulary, it shows the correct text. If I copy and paste it to this dialog box, it will display properly in the dialog box but then morph. Here is "Kāfēisè" copied from the screen: "Kāfēisè". The former words were copied from Google Translate.

Thank you Rocket Languages for fixing this. Actually, it was fixed months ago.
