Composer view credits alphabetically previous composer with first song of alphabetically next composer
I only use composers for classical music. This is a problem that affects some composers but not others. To be specific, I have several composers whose first names begin with A-C. Then I have the following: Delphin Jean Alard, Domenico Scarlatti, Edvard Grieg, etc. Starting with Alard, the last item listed under that composer actually belongs to Scarlatti; then, the last item listed under Scarlatti actually belongs to Grieg; then, the last item listed under Grieg actually belongs to the next composer, etc. etc. etc. Every once in a while, this problem "leapfrogs" over a composer, but for the most part it starts with the D's and goes through the end. What the heck is going on and how do I fix this?!
I'm using iTunes 12.3.1.23 on Win7 64-bit.
