The sample data will not help me as it could mess up my terms.
The way I am adding terms is by selecting the Taxonomy, adding the terms as below, selecting the parent and “Create inexistent parent terms” option.
Maserati/A6GCM
Maserati/A6GCS
Maserati/Auge
Maserati/Barchetta Straale
Maserati/Bi Turbo
Maserati/Bi Turbo Spider
Maserati/Boomerang
Maserati/Bora
Maserati/Coupe
Maserati/Ghibli
Maserati/Ghibli Spider
Maserati/Gran Turismo
Then click the btn “Add Terms”.
BTW: The parent chosen for the above terms also has parent.
