My Question or Issue

Why do i have multiple SAME songs from one artist? for example, i have 4 IDENTICAL 'STITICHES BY SHAWN MENDES' and many others... this then doubles my number of songs saved. and when i try to delete one of it, it automatically deletes the 4 copies of the song all together. My suggestion is that cut out all repeating songs, and if the song is saved again just out it at the top of "Liked songs" playlist. This has been bugging me for years. attached a few pics as an example.
