radio and checkboxes above labels

Hello all,

Here the code:
[radio belangrijk default:1 “Prijs” “Onderhoudsvriendelijk” “Duurzaamheid”]

I rendered this via the contact form 7 insert options. I read that the default output must be inline but mine seems to be put under each other. which is not a big problem but also the label is put underneath the radiobutton.

thanks in advance.
