If you want to get a smooth effect where that scuff is, lightly dampen down that small area, let the moisture absorb into the fibres for a few minutes and then work the area to a smooth surface.
Rub the dampened fibres vigorously and the fibres will pack down smooth. Finish with a light rub of Proofide over that small area.
I use a bookbinding 'bone', but the back of a spoon would be adequate for that spot.

Do a search on 'leather slicking' or 'leather burnishing' and you will see the technique.

And update this thread with your results.
