Hello,
It’s there https://gyazo.com/2149a4e1f5f3f1bcfe62508c43bcddf6
And it’s set to Copy once, you can unblock and change it to Copy if you need.
Anyway, you choose the sidebar position globally in Theme Options > Blog > Blog page > Sidebar position or manually in the page settings https://prnt.sc/12ve9o9 and also you set translation for these custom fields either globally https://gyazo.com/2149a4e1f5f3f1bcfe62508c43bcddf6 or manually https://prnt.sc/12vearr
And everything works.
Regards
