When using the dashboard /api/import/swagger/ for updating an API as well as via the UI i get an succesfull response. result : {"Message":"API imported","Meta":"","Status":"OK"}
But the API NAME field and the Category are not changed accordingly.
I would expect that all all fields belonging to that apis internal id would be changed (as stated in the docs https://www.tyk.io/docs/configure/import-apis/
‘insert_into_api: If set to true the import will replace an existing API.’
