Can't make it work

Hi

Thanks for all your work,

i’ve an issue about buttons. It only allows me to choose style among simple and i can’t make anymore “tuning” of the buttons..
That’s so emabarassing !

(obviously I can enter name and link, and position in the page (justify,center..) ) But I don’t have all the useful options I saw in the demo ??

do you know how can i Fix it?

thanks !
