No, that's fine. That's how it should be. The only time I've had it spray out on me is when I followed the directions to "shake well". I did that, and opened it and had an amazing yeast fountain/shower. I now shake it up to mix, then ever so gently open and get a small "pssftt". Then, I open it the rest of the way. There's no reason for it to be under pressure, so it sounds like it went just fine for you.
