Help with CS1 add-ons on PS4. Has add-ons installed, but not downloaded?

I play CS1 on PS4, and want to get rid of the christmas music. I tried deleting the game, but the game still remembers the add-ons. (saying they are still installed, even when the game is redownloading) I bought the Mayor's Edition a few years back because it was bundled with some useful add-ons, and would play off and on. But for some reason the console, and game when loaded says I also have Pearls of the East installed much like Christmas DLC, even though the PS Store says I can download them. I never downloaded these DLC, and they aren't included in the Mayor's edition bundle.

I wouldn't mind the christmas music if it was on it's own radio station. BUT IT IS ON EVERY SINGLE STATION. It's so jarring jamming to my radio tunes, and then christmas music pops up. IF I WANTED TO LISTEN TO CHRISTMAS MUSIC I'D LISTEN TO A CHRISTMAS STATION. What's the point of having a radio station at that point? They aren't even in the same genres of music either. (I listen mainly to Synthetic Dawn.)

Is there anything I can do beyond factory resetting the PS4 to delete these add-ons attached to the game? Because I may as well not play the game anymore. (Or wait until December has passed, if it is a December only DLC) Turning the music off, may as well mean turning the game off for me. (Cause you know console)
