Face animation doesnt play in build though body animations play.

I work with VRTK 3.3. and SteamVR Plugin (for HTC VIVE). I have humanoid characters (MORPH 3D), which they have body (2nd layer) and face (Primary layer) animations. In the play mode everything plays as expected. Though, when I build the exe (I tried every compression mode) the face animations do not play in the exe , just the body animations.

I believe is a build problem but I dont know which options to tweak. Till now I ve tried : API (changed it to net 2.0 instead of the subset) , Blend Shapes ( tried all of them, 1, 2, 4 bones) , all the compression methods ( def, LZ4, LZ4HC) , quality settings (tried fastest, normal, Fantastic), Animation Debug settings (tried Legacy nothing. Actually it is better unticked, all the wrap modes again nothing). So I really dont know.

The version of Unity is 2017.4.8. I have tried to downgrade to other versions (all 2017) and the problems persist. In 2018 versions the project breaks all the textures so this is not option.
