Do you have a maax neo angle shower & if so....?

does it have glass corner sheves? i just purchased one with the glass shelves and because the glass walls can go either way when installing it they put holes for attaching the sheles in the glass at both top and bottom. so to waterproof the bottom holes they seem to provide stupid little white buttons that are too small so i think they will leak. anyone have any experience with this model? called YARROW by MAAX
