How much scent did you put in vs how much the wax will hold. If you put too much scent in the wax can become a fire hazard.
Also, I have found that just because a wax can hold a certain % of fragrance, most waxes don't need near that much to have a great cold/hot throw. I've even found that if using too much fragrance, it has the opposite affect, and will actual hinder the hot throw.
Nona's advice is good, but if it's not needed then I wouldn't do it. All depends on how much you used in the first place. When I worked with joy wax I found 4% fragrance load to be plenty for most scents.
