Kalam is away, so Arked has taken over the responsibility of managing the banner pack. Unfortunately, this means that the banner pack linked in Kalam's original post is outdated. Just because Arked is in Shogunate does not necessarily mean that his banner pack is EU and Kalam's banner pack is NA.
Also, if you take a look at the file name of the download link quoted in my previous post, it says "Kalam's Banner Pack v3.5" and not "Arked's Banner Pack v3.5"
Thus, there is no reason for you to be using the "NA" banner pack, which is just an outdated version of the banner pack shared by NA and EU. If you actually installed the latest version, you would see that the banners included are of both NA and EU clans.
(I'm NA, by the way)
