This only happened once and I don't have a lot of information about it, but here goes anyway: One time on the character select screen (I was playing as SMAS SMB2 Mario on the SMAS SMB2 Map Skin, and I think it was World 4-2?) I noticed that while most of the character portraits were the default SNES versions (since the console was set to SNES), Sophia's slot was showing Jason's NES portrait. I selected Sophia to see what was going on, and I saw that it defaulted to SNES Sophia, but still showed the NES portrait. However, when I moved away from that skin and then back, it switched to the SNES portrait. Sorry I couldn't give you any more information, but it wasn't a major bug anyway.
