How can I define sorting layers for meshes w/ orthographic camera?

Does anyone know why the orthographic camera is rendering my grid meshes below the ground sprite on the top half of the camera view, and in front on the bottom half?

Is the ground material set to “Transparent”? if so, set it to opaque or decrease its Render Queue value (Sorting Priority in URP/HDRP), if you need the ground to be set to “Transparent”.
