I used Google Translate to translate your message, here is what I got:
Wrong name when confirming order and opening an account
For about 2 months now, an incorrect name has been displayed when placing an order or opening an account: It always says: Hello Jannik
We have already supplemented the templates, but this name always occurs and we do not know where it gets the name from !?
Could you please help us?!
It looks like you have tried to upload a screenshot, but I don’t see it, unfortunately. Can you please try to post it once again?
And can you please provide a link to your website in order to let me check it? You can use some link shortener if you don’t want to leave the link to your site in this topic.
Kind Regards, Roman.
