checkbox display problem

Hello,

I have a display problem on a contact form at the bottom of the page, I can’t make a checkbox appear
When I integrate the [acceptance] tags the following RGPD message disappears: By filling in the form, I accept
These tags are supposed to show a checkbox on contact form in wordpress
Do you have a css code to override it.

thanks you
