In what load steps were these loads applied? You should not apply them all at once. For bolt pretension, you should only load the bolt pretensions in a 1st load step. Only use enough supports and displacements to hold the model from rigid body motion in that 1st load step. Then in 2nd load step and any later load steps, you can "lock" the bolt pretension and apply your other loads.
