AllTrack is only able to pay you royalties on Live Performances of your original songs. If you mostly play cover songs but mix in the occasional original song, you are entitled to royalties specifically for the original songs that you perform. Make sure you report complete setlists to AllTrack, including covers you perform, so the original creators can get paid royalties. If someone else performs your live songs and reports them to AllTrack, you'll get the song royalties.
You can log in to your account to report your Live Performances here.
