I just found this:
The German propaganda in the loading screens shows us a big German war flag and the text: Einsatz, Der Deutschen Kriegsmarine (but we can only see Eins, Der Deutschen Kr), but Kriegsmarine was the name of the German navy during WW2, the Imperail nay is called Kaiserliche marine! So the one who photoshopped the war flag in it (great work btw) need to change the R to A or hide the R behind the Canadian poster. Also the flag on the ship uses the nazi flag so that could also be done then.

Good catch
