Howdy guys!

I need a bit of help with a geometry issue which I've never really asked about but you'd think I'd know a solution to. I am working on a circular table and for the most part it looks good except for the top of the table. Since it's round I have the layout looking like this.

But when I choose to look at the mesh preview the center piece right there in the middle turns into this weird, star shaped like thing here.

I know it's caused because it's a single face (if I remember correctly) but I can't figure out the best way to resolve this issue. So if you guys can tell me how I might correct this I'd appreciate it.

Thanks Much!
