Why are old songs being linked to new songs????

Uk rapper nemzzz just dropped jis new album a day ago and theres this hefty glitch that isnt just affecting me but others too where old song from his old tape ots somehow mixed, merged and combined into the new songs so now the streams for the new tracks gets allocated to the old tracks even though you're not hearing it. Basically the streams for the new track are dissapearing, aint registering and instead goin to old tunes that havent even been listened to
