How to correctly use cyclic BCs ?

Hi all,
I want to simulate the advection of an Euler vortex as shown in this paper. I correctly initialized fields in 0/ directory but any solver I used failed to correctly move the vortex as it should be (I used rhoPimpleFoam, rhoCentralFoam and now I use pimpleFoam). I attached the case to this message.
I suspect the issue has to do with BCs. I set them as cyclic because in the paper they are periodic. What's wrong in my case ?
