Static Riks results for load vs angles , load vs lateral deflection and load vs vertical deflection

I have differenet layups for cantilever beams. I run the static riks test from the eigen value in the first software ,giving values of initial arc increment of 0.005, mimumimum arc length increment as 1E-35 , maximum of 1000. The static riks gives good results for the notional loads for layup 30 -30 30 -30. However, keeping all other parameters same but for a different layup 30 -30 -30 30 ,the values from the staic riks are very very far from the experimental results. The values from the unique nodal for displacement is in the range 0f 10-3 while the values I get for lateral and vertical deflections are around 300 mm and 67 mm for the layups.

What parameters do I need to change so my values are close to the experimental results?
