Weird behavior of the grid

I’m facing a weird behavior of the subgrid with dynamic paging mode.

I’m using a grid with sub grids and every time I try to go to next page and click on (+) sign then the subgrid behavior weird and the subgrid show on the top of the parent grid for all and overlap the rows of parent grid and could not collapse.

Thanks in advance.
