You still have plenty time to correct that, which you should. Malpositioned or detached air cells can cause problems for the developing embryo, causing malpositions and problems when they need to hatch. Approximately 2/3's into the incubation the embryo will position itself in the egg to pip into the fat end of the egg, where it will be expecting the air cell to be. If the air cell is not there when it pips internally, it may drown or suffocate in the egg.
What you can do to correct the air cell position is position the eggs upright, with the fat end up. The air cell will slowly make its way up, into the highest point of the egg. It could take awhile, though, so the sooner you turn the eggs, the better. Once you got them upright, you'll need to tilt them, instead of turning the eggs, as you would when they are lying flat. Start by tilting the eggs at a 45* angle, then after a few hours tilt them again, in the opposite direction, again at a 45* angle, so the egg does a full 90* tilt. Repeat every few hours, until you lockdown. By the time they go into the lockdown the air cell should have reattached and you can lie the eggs flat again, for hatching.
Best of luck with your hatch!
