multiple values under a data field

This is my json:
https://telessaude.ifes.edu.br/salus/api/v1/estatisticas/visao_geral/

This is the code in wordpress:
[jsoncontentimporter url=”https://telessaude.ifes.edu.br/salus/api/v1/estatisticas/visao_geral/?format=json” basenode=”total_mensal”]
{total}
[/jsoncontentimporter]

And this is what I got in the frontend:
http://telessaude.ifes.edu.br/json-teste/

As you can see, this code returns all the values for “total” under “total_mensal”. But I only want show one of them, for example the second one. Please, If someone could help me with this I would really appreciate…
