In the English rules, the board is completely set up before the players get their starting wealth tiles. So the online implementation is correct.
"After setting up the game (including revealing buildings
and monuments) mix up the Starting Wealth Tiles and deal
4 secretly to each player."
Thank you, I missed this somehow when re-reading manual and got confused.
Thanks for quick reply!
