Hello! All the settings for import and export are covered here:
https://wpgeodirectory.com/docs/core-export/#import
I would recommend that you do this manually if you only have a few listings, as seems to be the case. The issue is that on the Spanish listings translations, they are in the category “Restaurants”, but this category does not exist. There is instead a new category “Restaurantes”.
If you want to try the import method, then, you are ‘updating’ the listings, not importing new. The only think you need to change is the spelling of that category in the CSV.
If you have any doubts, then I recommend you set up a test site where you can try it out first. If you need help with that you can contact a GD Expert here. https://geodirectoryexperts.com
