CST - Error in system assembly and modelling in CST STUDIO 2023

while using assembly mode in CST Studio Suite 2023, how is it that we can fix the orientation of a component and one other problem that i faced in assembly mode while doing the optimization task , i get a frequency based error i.e. after a number of iterations in optimization it automatically changes the frequency limits of one of the components and then gives the error of frequency mismatch. How to fix both these issues?
