Hi,
In the current version creating two dependent Select fields is not possible unless one of them is the listing category. If you already created a single Select attribute for the Make/Model with hierarchical options (the one on your screenshot seems to be ok, it lists makes as parent options and models as child options, so it’s not possible to select BMW > Logan.
To display both values, please try this display format: %parent_value% %value%
. Then selecting Toyota > Corolla will just display Toyota Corolla on the listing page.
