NavMesh bugging after Player hits an Enemy

Hi, I am creating a simple shooter prototype.

My Enemies have to move near to me (Using NavMesh) and to shoot when they are at range.

When my Player hits with his body to my Enemys, he pushes them, but they bug and cant recover the route to the player.

¿Does any1 know what can be happening here?

I am having the same problem, it probably have to do with the Rigid Body, RB and navmesh don't like each other...
