I have a database of 5,200 films (2,600 seen and 2,600 to see) and from my experience in working with AMM I caution you about changing the assigned primary genre. I know you want a clean database but you also want one that is easy to manipulate.
Changing the primary genre will cause a number of problems like the one you already experienced. I created several new genres, e.g., historical drama, musical (before IMDB added that to one they already had "music"), detective, classic, silent, foreign language, based on a book, based on a play, etc. and these, although very helpful, do cause problems when updating genres from IMDB. In fact I just finishing removing all my historical drama genres and using IMDB's uninspired and uninformative drama and history genres combination. Every time I updated a film using batch item update AMM would insert the IMDB history and drama genres so I decided my editing efforts for historical dramas was being wasted.
It appears that "additional genre" entries from IMDB are added to AMM data in alphabetical order the first time. If user edits them later the ones user adds usually end up at the end of the list. Think of the additional genres as general genre indicators and not as position indicators as to importance.
