Album count discrepancy

Has anyone noticed that when grouping albums by Genre, the total number of albums in the Library does not match the total number of albums when not grouped? I wonder if this is a SQL Lite issue or something else? Currently my total album count increases by one when grouped by Genre.

Hello, Jim_F,

I great hypothesis and I appreciate the idea; however, I manually assign a single genre to each album and never assign two to an individual album.
