Shuffle not working as intended

When I use https://music.apple.com

Select Library -> Songs, click on a song and then press shuffle.

If I select a song starting with letter A it will only shuffle songs between songs starting with the letter A and B. Likewise if I select a song starting with the letter D, it will only shuffle songs between the letters D-E.

Shuffle works but only selects a small sample of songs out of my whole library, I want to be able to shuffle all songs.

Only had this problem on the website https://music.apple.com not on macOS or phone & ipad

Would love to see this fixed
