Songs not shown in library

Hey everyone. Recently, I transferred my playlists from other streaming service. The problem is that the songs are not shown in library when I search for them. For example, I search a song which is shown in a playlist, it is shown in Apple Music tab search but when I press the library tab it says that no song found. Even though it is there… the songs added after the transfer, are shown in search results in library tab… has anyone dealt with this in the past and is there any way to fix this?
