Unable to select different leagues when starting a save

same happening to me, but only when using "your world" option, over modes is fine. 

Same with a Belgium, Germany, Netherlands save - Again in your world - selected to start in belgium early preseason - unable to switch to other nations

Hello, this is actually working as intended, this was done to prevent circumventing the link between transfers/budgets and start date. You would otherwise able to say start a game in Brazil December 2022 with the Database accurate to Summer 2023, which would cause quite a mess in the real-world mode. 

We are planning on making this change clearer to users, we appreciate you you raising this.
