This madness occurs when default album names that you create contain commas. Commas cause a very specific reaction in album creation – It's very important to remember that when it comes to album names, commas act as separators, and not punctuations. For example, if you create an album called "San Francisco, California" you will end up with two albums – one called "San Francisco" and a second one called "California". If both are set as default albums, your incoming entries will automatically be replicated and placed in both albums. So the moral of the story is, never ever enter commas as part of an album's name. Only use commas to separate names of different albums.
