you will probably need a fluid dynamicist to give you the full answer but it is down to surface tension. the bubble solution creates a surface tension in the water whereby the bubbles can form and hold, the soap alters the surface tension so that the bubbles can no longer be sustained

na na.

soap reduces surface tension, allowing easier bubble formation.

soap products contain anti foaming agent for environmental reasons.
