He specified the soil class as zc and z3 in the design spectrum parameters and Foundation-Soil sections, is this due to the transition from 8.6 to version 10? Has the article "Increase the soil safety stress when using earthquake loads in the new regulation" been removed? I did not see it in the program. The program adds a line related to this item while getting the report in the 10th version of the project that I previously drew in the 8.6 version.
