It isn't actually a problem. Guth and Turok contradict each other as well. Which, if either, of their hypotheses actually reflects reality remains to be seen. It could well be that elements of both are true, or neither. That's why they're active areas of research. The same is true of competing hypotheses in abiogenesis. I'm still not sure why you think this is remotely a defeating argument. It isn't.
