who's to say that's a bad thing? american or british english isn't superior to african english, and in some cases, english like this can help us get the mindset of a speaker of this language. This isn't a matter of what dialect they speak in but just a matter or how negligent people can be.
Glad your issue has been fixed now.
I don't think that the issue is whether British or American English is better or not, it is more that it's very difficult to learn the language when you are also having to learn the translation because it uses non-standard grammar structures. That's not to say that the non-standard structures are wrong, but that several options for right answers should be available to facilitate learning.
