While the faces round the rim and on the inside bottom are missing because they're too small for SU to create them, the face on the bottom isn't missing for that reason. It is missing because Follow Me is subtractive when there's already geometry at the location. You left the face of the circle for the path after drawing it. Since there's a face there already, it gets deleted during the FM action. Delete the circle first and then run Follow Me. You'll find that the bottom of your bowl is then made just fin.
If you're going to scale up and scale back down, there's no need to make the thing a group first. I frequently draw small details that require scaling to get faces to complete. I make a component of the entire geometry, copy it and scale it up as needed. Don't open the component for editing before scaling. Then I work on the large version and when I've finished, I close the large copy and delete it. This leaves the original in its original location with all the tiny faces created.

This is after scaling a copy of your profile up by a factor of 10 which was enough to get faces made.
Leaving the original in place and working on a copy is especially useful when the original is already placed where you need it because you don't have to spend time putting it back. This idea is useful for more than just Follow Me operations and you don't always have to scale the copy up.
