Tchaikovsky - Album View - confused on information showed

If you search for Tchaikovsky , the resulting screen is:

Case 1
If I now click on the Album - View All


then I get the following result: 38 albums - 7 in my local storage, 31 in Qobuz

Case 2
If I go back to the Search Screen for Tchaikovsky, and select Top Result : Composer


I then select Performer (at the right of the screen:

I get the following result: 48 albums

(If I go one more strp further and click on View All Albums at the right , 80 albums are displayed)

Why these different results, and more explicitely : why in Case 1 are only 7 of my local storage albums displayed.
I am rather confused by the different information showed.

Any insights will be very much appreciated.

Most likely, Tchaikovsky is tagged as a “performer” (probably Album Artist) for a large portion of the larger set.
