Brim Settings problems

I’m having problems with the print and people in the Fusion forum are suggesting I’m having problems with the brim settings, but I don’t know where those are. I am running Creality Print slicer Version 4.3.8. Are they under some different name and how does changing them affect the final print?

In an effort to make my previous post, more understandable I’m adding a picture. The ring on the right is what I’m trying to produce, but I need the material to be stiffer so in the effort on the left (which wasn’t completed to save filament) I have simply increased the outer wall to 2 mm. As you can see the outer wall is no longer connected to the infill. What am I doing wrong and how do I fix it?
