Clamped Actions Between [-1,1]

[rogerpm3]

I have an issue exporting a trained model as with the following configuration the actions values are clamped between [-1 , 1] (I don't understand why but also happens with all the other examples) I can work with that, however when exporting I get values with no limits so it's no use. How can I solve this.
