Different albums same location

It is very annoying that with the same album name, completely different artists and different styles and metadata are placed under the same album. Please fix these errors. iTunes solves it very easily if the compilation’s window is checked, it only puts it in the same place.

By the way, it would also be good if I have already added an album and i try to add again Audirvana indicates already it has in the library (my music has on different hdds )
