The last photos shows a close up of the underside of the plate and the raised center portion. This appears to be somewhat crooked I believe.
I place a small, clear silicone wedge under the center and it no longer wobbled. The lines in the bottom of the bowl are from manufacturing , not a crack. See image # 10 for a close up of the bottom.
