Are you sure that two restraints were placed in the model?
The output would show both FX and FZ reaction for a single, skewed, restraint. The load should show that FX=FZ since you put the restraint on a 45. The deflection, too, should show that relationship: DX=DZ.

Now, you also say the restraint is in the "-X" direction. You should show that negative sign in your restraint definition (e.g. +X(-.707,0,.707)). If the restraint is "active" in the load case you are looking at, what I said above is true. If the support is inactive, you will have no restraint load and no predefined relation between DX & DZ.
