Pole Beans not Producing

I have a teepee of beautiful pole bean vines- Kentucky Wonder, probably 8 vines total. Grew like crazy. Seeing flowers. No beans. Zero. I have another vine in a different part of my garden (accidental seeding!) and it's producing beans! I planted the beans after an early pea planting, and I have a winter squash, Delicata, growing in the same spot. I've seen some beetle damage, but nothing major. It's hot here in TN, highs in the 90's, lows in the 70's. Anybody have any idea what's keeping my beans from growing beans? I'd love to have the problem of too many beans! Thanks.
