Wood Finishing

I have a chest made out of walnut that I am finishing. I used tung oil on the walnut and after it dried for 24 hours I put a coat of quick drying polyurethane and let that dry for 24 hours. I sanded lightly with 320 grit sandpaper and applied the second coat of polyurethane. Here is where the problem is. On the second coat, there are places where the poly separated from the first coat and left what looks like a "dry spot". Has anyone had a problem like this and what did you do to prevent it from happening again? Thanks for any help you can offer.

Welcome to the forums!
It might be a soft spot in the wood that needs more poly to seal it.... assuming it isn't as slick as the rest of the wood.
