Hi Candle guy. When I use 4627, like debratant, I did not notice bubbles either. Nor did I have the to do a repour, (I just double checked candles I made in this fall, they are flat on the top), that was one of the reasons I like 4627, I didn't have to do a repour and saved a step. I heat to 185, (for me this wax melts quickly and smoothly) add dye, then fragrance, stir 2-3 minutes, then pour right away. I did not wrap them, just let them cool at room temp. I haven't had bubbles, but I do have wet spots. Perhaps you are right, the ambient room temp. may have been a little too cool.
