How come ice cream is soft when frozen but after you melt it and freeze it, it becomes ice.

It has nothing to do with bubbles or air.
When water freezes it forms ice crystals and if undisturbed these crystals can get long and interconnected. When ice cream gets made it is continually stirred and this stops the crystals from getting too long and sticking together. If you stir your ice cream while it freezes it goes back to the soft texture it had when you bought it.
