It is just the North American pronunciation.
Another example, Persil detergent has just been launched over there. We say Pur-sul, they say Pur-seal and the ending sounds really pronounces as in seeeeal - sounds wrong
.
There are loads of brands that are pronounced differently/wrong. Miele is a good one; from meal to mee-lay (it's mee-ler).
Best one (and had it hundereds of times in the course of my job), the phone brand Huawei (you'd expect it to be Hu-way/hu-wai), I asked the manufacturers when they were in the office, it's wow-wee but add a h sound just before saying the wow.
