I have been very busy lately and apparently missed this thread completely.
The AJ country tag was made for anime only.
It is when an English dub is made of an Japanese anime and they make some changes so the guide would be a mess if we tried to add all info to one guide, and we have someone willing to keep the guide updated.
This was done years before we added the feature Alternative airdate (for when a show airs in another country).
We are developing a new version of the site and this needs to be discussed how will handle shows like these in the future.
tldr; AJ - English dub of an anime that is airing in USA.
Also, if a thread goes unnoticed always feel free to send me a PM and I will get back to you as soon as possible
