Bugs new version

a) I added some custom fields, and it works normally. But when I go to insert them in “All Listing Layout” > Grid View or List View, the data from the custom fields disappears or duplicates when I save the changes. Check the link in the image.

b) I tried creating a new website by importing the settings from a saved JSON file. It always returns an invalid data error. No imports worked, from the site listings and settings.
