No Specular on Dynamic objects when using Probes & Directional lightmaps

Hi all,
I made a forward rendered Scene, with Directional lightmaps & Probes. Everything is working properly (for both Static&dynamic objects, and since the 1.04 dynamic shadows with auto directional light :) ...), except for the Specular/Glossiness informations on Dynamic objects.
Am i missing something ?

I work on the last Unity update.

Thx !
