A few on mine do it even when grown in a pot.
Next planting cycle you can move them away from the structure a few feet and see it that helps.
They bend pretty quick when the container tips over too so do not let a plant lay on its side too long.

When you pot them up soon for the winter just straighten them up in a container and they will sort themselves out in no time.
