Help! Polyurethane Problems!

Hi, I recently decided to re finish a solid oak kitchen table. I have completed the stripping, sanding and staining (minmax black walnut stain) process now I have moved on to using a minwax oil based polyurethane. I have applied two coats already and I have small un polyurethane areas everywhere (see picture)! I realize the poly is not supposed to soak into the wood but it is as if its not adhering. I don't want to strip down this table and start over. Do I have any other options?! Please help!
