I recently got my swift mini. The automatic tamping has a problem. Some coffee powder will be built up at the edge of the filter basket. I tried all of the 3 baskets come with the grinder but the situation is the same.
Check out the La Marzocco Swift Mini Review for some usage tips. The dosing goes by the level (not weight or time), so how well the basket fills (or not) matters. Judging from your photo, I would check if the discharge tube is clogged; if you raise the grinder section like you're grinding for pourover, you can easily check visually without removing the dispersion "fan".
Did you get any resolution on your problem with the Swift Mini? I have had mine for about two years. Been happening on and off starting about a month in after purchase and now more frequently.
