How long have you been allowing your candle to burn at a time? Most candles have a minimum length of time that they must burn in order for the wax to melt evenly. If you are burning your candle for a shorter period of time than is recommended, then the wax near the wick is melting, but the wax further from the wick isn't getting hot enough to melt. It takes time to heat up the wax near the outside edges of these candles.
