I'm facing an issue further to data migration from magento 188.8.131.52 to 2.4.2 in Admin > Store / Configuration / Category
Categories name and url_path are in the database, Category name also.
Category names are well displayed in navigation tree on the left but Category Name field and Search Engine Optimization > URL key remain empty...(see pic)
All categories url are broken (404) on front store
When I try update data manually in empty fields, I've Error on save : "URL key for specified store already exists." cannot save category" with empty url '.html'
Of course all reindex, cache flushing etc have been ran.
If you have an idea to fix it, that would be great !
