Sounds indeed like the language of the user is not the language in the modeller.
Try switching to the other language in the modeller.
Bart is right. You're looking at the deployed application in a different language as in your modeler. Right next to the deploy button you can switch your language settings. Try another language in that dropdown and you will see the <>. Or you could change your language in your deployed application if you have a form where the user can select his language.
