AR plane overlap one another after detection

When I am start detecting the AR plane some times detected AR plane may cover the other tracked AR plane.
Like When I’m start tracking the AR plane it will detected a single plane but when any object comes in front of tracking the single plane it will split the AR plane into two or more pieces but sometime it is covering already tracked AR plane may overlap with one another.

@ajinkya446 Hi, did you find the solution to merge planes?
