Hello Marvi Gover,
As far as the problem is concerned i do not find any such thing related to optisystem version 14. I think as suggested by Mr. Umer Ashraf , you should try to uncheck the “generate random seed” option for every active component and then recheck the results. The has been a common problem but the results do not vary to an extent as you have said. Still i think you should give it a try and see if it helps you. I hope it does. Thanking you.
Regards
