Default Minwax fast drying polyurethane dries to white haze

This JUST happened to me? It is the oddest thing! I have never seen this happen before. I had stained my fireplace, waited a few days...then put on the polyurethane and it streaked it white...as if I had let water sit on it or something. Did anyone ever give you a reason why this happened? I have used the exact same polyurethane before and the product was great. I am so confused...hence I googled to see if anyone else has had this problem. Let me know if you have any answers.

well, it's fast drying. So it has no retarder, or has a lot of driers
(metals).

Generally is sounds like a humidity problem. Too high to use a fast
drying product. When the humidity is high, a retarder is generally used.
If you use a fast drying product, you get a haze.
