Hi all,
I have started creating a new app and opted to use Strapi, however I have an issue with i18n and some of the types.

First issue around i18n is that when i try to change internationalization i manage to select one in the dropdown but fields (which do have an internationalization enabled icon) are prefilled with data from the old locale. when i change and save something the original locale changes as well and i don’t have a different version of the locale in my db.
Also when i click fill with another localization I have nothing to choose from.

The other issue is that single types crash the admin page (and all the queries) for some reason.
I can build a type but when i try to get to it through content manager i get a blank page with a 404 issue on console, and an sql issue on backend. I tried creating a new single type but same issue. another single type (with the same fields works fine)


These are the rest of the screenshots
