Some border when exporting to PDF

Hi! I’m learning to use Figma for little things, my father has a little business and i wanted to do a Business card, but, after finished i tried to export to pdf and it adds a strang border around some vector, i don’t know how to remove it, or what i’m doing wrong. I will put a snap of it for people to see.
I will be greatfull if someone can help.
