Converge in Dense meshe, Diverge in less mesh, but correct answer in less mesh!?!?

I am working flow over cylinder 2D with fluent and my purpose is that show the vortex shedding behind the cylinder.
I meshed the domain 2 times. First I meshed dense and my solution converged but i couldnt see the vortex shedding. I should mention the my fluid is air and the velocity is 0.002 so that my Re=137.
The solver is Laminar, steady and etc.
next time, I changed my meshing and change to less mesh than before after that my solution didnt converge but i saw the vortex shedding behind the cylinder.
I attached the figures of my solution in both cases and my meshes in both cases.
does anyone know the reason of that?
Thanks in advance.
