Wiserarm Sandero – Misconstruction?

Hello everyone! For a week I have a Dacia Sandero and wanted to remove the lone wax from the front window today. Now I have the salad. The wiper arms can not be opened properly, about 30°(of course not Celsius…) against the bonnet. So…and now is paint damage! Is this also the case with you sander drivers? So with all the cars I had and which I know is not so and yet not normal, or? Thanks for your answers in advance, Greetings -Micha.
