Some songs are not showing in the search bar

[Sfeerr]

Hello, when I search for an artist in the search bar of my playlist, some songs are not showing, but when I search the album the songs are showing, thats a very strange bug that happens on mobile and PC.

It happens for some artists in my playlist only but its still annoying.

Thank you.

In the first screen a album search:

and in the second a artist search:

It happens with most Metro Boomin albums too
