Turning off reverse card

I have the Beautiful Basic & Reversed Cards Template from Anki Decks and now I would like to deactivate that always two cards are created - so I would like the design but only one “basic card”.

That note type seems to have two card templates - but you only need one.

Head into the Cards... editor, open the dropdown menu on the top and select the second card template, then click Options (top right) and remove that template.
