OK, sounds like a good plan, if maybe unnecessary, but I guess it is better to be safer than sorry.

I have solved the first issue using this Action:  
Format Value:  
Field: Genre  
Format String: $trim($regexp(%Genre%,'(?:(?\<=/)|(?\<=\A))\s\*([^/]_)\s_/(?=._?(?\<=/)\s_\1(?=/|\Z))',,1))

This will get rid of the duplicates in Genre.  
I got it from here [Merge duplicate words - #10 by dano](https://community.mp3tag.de/t/merge-duplicate-words/16289/10)

I really hope I can figure out how to propagate the specific genres from the Genre field (My second question) as I stupidly erased them after consolidating them in the main Genre field. I will play with abelcheung's suggestion and see if I can get something working.
