I have had that happen, particularly with demisphere molds (which is what yours looks like). Did you also have the issue that when you are adding ganache (or whatever the filling is) the chocolate shell can be dislodged easily? That is also a characteristic of flatter, spread-out cavities (while being an inconvenience, it is also a positive sign that your chocolate was in temper and is going to come out of the cavities easily at a later stage of the process). As for the chocolate showing around the bottom of the finished bonbon: I have always assumed it is because I did not completely cover the cavity with colored cocoa butter--that is, up to the very top. If you leave any spots unsprayed, they are, of course, going to show the underlying chocolate color--it's easy to miss this when you are in the process of spraying and you don't want to make too thick a layer of cocoa butter and you are hurrying because the cocoa butter may be getting too thick or cooling too much. The gap in color could also happen when you scrape after capping the mold. Not everyone agrees with the following, but I think you need to scrape off all the excess cocoa butter after spraying the mold so that you have a completely flat surface when you pour and scrape what will become the bottom of the cavities. Immediately after spraying a mold, I invert it over paper towels and rub it back and forth to get off as much c.b. as possible. Later I use an offset spatula and paper towels to clean off what I missed. Experience has taught me that leaving any bumps of c.b. will make scraping uneven.
Yeah, it's a demisphere. When you mention it, I never had as much chocolate showing on the edge as with this one. I thought it might've been that I scraped some of etc, but it doesn't seem to be the case - and the suggestion I got was that small amount of chocolate manages to get between the mould and the chocolate shell. It kind of make sense, and if you look at the picture below (right side), you can actually see that there's a small layer of chocolate on the edge of the shell. It wasn't dislodged easier than usual this time, but I've had times where the shell moves around when capping.
